"National has become a major manufacturer of computer systems. IBM-compatible mainframe computers made at the Company's facilities in San Diego, California are used in more than 100 locations throughout the world. Excluding IBM, National is the largest maker of IBM-compatible mainframe computers in the world."
"Experience in producing and marketing IBM compatible add-on memory systems and a 2-year manufacturing history in IBM compatible mainframe computers as encouraged National to take the next measured step of selling IBM compatible mainframes direct to end users. The San Diego Facility that has shipped over 300 computers will be the source of National's new NS8500."
You can see the 2x3 foot wirewrap panels which were the circuit boards. If I recall correctly, my XAR was the bottom board on the first door on the right side of the computer. IBM had designed, and we duplicated, an ingenious serializer which read out hundreds of internal signals and displayed them on the CRT.

This was my cubicle in building 1 in 1981.
Each gate array was mounted on a carrier board.
The carrier board was then plugged into the Printed Circuit Board (PCB). This was done because of the difficulty (at the time) of routing signals between the pins of the gate array if it were on the main PCB.
This is the main memory ECC board for the system. Each gate array processed 8 bits of a 64 bit word. All 8 gate arrays on this board were identical.

This is the first machine we shipped. Its the big blue box. The AS/6130.
This is our engineering model. It's the one we spent 3 years working on. These were real printed circuit boards which plugged into a backplane. During debug, we had engineers working four 12 hour days covering 7 days a week. Debugging went on for over a year. At least we had a logic analyzer (bottom left). This workarea was in building 3.
The design was synchronous. The black wires that you see interconnecting the boards were the clock distribution network. There were strict rules about clock distribution so that every flip-flop in the computer was clocked at the same time.
This is a picture of some members of our engineering group which worked on the first shipped machine. That's Allen McAfee in the lead. followed by Julie Lilly. In the back, I recognize Chun Lee and Kirby Spalding. I don't recall who debugged this particular computer. It may have been the engineering group or it could have been the test floor crew.
This is the ceremony which marked the first shipment. That's the division general manager, Bob Spencer, addressing the "troops". That's me (Mark DiVecchio) on the right. The blue box (not the dumpster!) is the AS/6130. The customer for this computer was Scripps Clinic and Research Foundation in San Diego.

Subject: How ya doin'
Just happened to run across your web page. Thought I could fix the fact that we lost touch.
I've been here and there since NAS & Megatek, and finally back to the east coast, Rhode Island (EMC & LTX), Conn. (to care for my in laws), and now moving to Maine. Divorced again, married again (to my high school sweetheart) for about 20 years now.
Like you, I'm "between jobs", would like to have a bit more fun before I hang it up forever. Things are disgustingly quiet so I joined a Volunteer Fire Dept. to stay a little busy.
That's about it, stay in touch,
Wow. Good to hear from you. It has been a long time.
As you could probably tell from my web pages, I've 'toughed' it out in SD all these years.
After NAS, it was a short stint working again and then I went off on my own. I had a small (usually 1 person) company named Silogic Systems for about 20 years. I did engineering consulting and logic design. In the early 2000's I went to work for one of my clients, AMCC, worked there for 3 years and then retired.
About half of the people in the old NAS photo are still in SD. The rest - who knows. Chun, John, Dave, Chuck. Gary and Julie are still around SD.
Kirby and Ralph are up in the bay area. I worked with Gary at AMCC . I see Dave Bilak at a Star Party that I do once a year.
If you want any emails of these people, I have a few.
I will forward you an email that I received in 2006 from a Tammy D'Imperio. She wrote me looking for you and I've been saving her email with the faint hope that you would surface - and you did.

I was searching for an old reference for EXSYSCO/NAS in San Diego and came across your web-site. I do not think that you will remember me but here goes; I am Walt Bonneau and was a Associate Engineer/Control Console Tech while at NAS from 1977-1980. As with you, I moved to Megatek in 1980 and remained there until 1984. I left San Diego for Texas where I worked for Texas Instruments for over 10 years. From there worked for Sony Corp for nearly 4 years. Created my own company which I sold, and joined Cubic Corp for the last 11 years.
I was simply amazed to see your web site and the family history as well. I took notice of the visit you took to Idyllwild in 1999. My wife and I have land up there and plan to build on it next year. I just remembered when I was a very young engineer that you were always very helpful.
Anyway, just wanted to say hi,

I decided for some reason to Google "Exsysco" and see what I would find.
Imagine my surprise to get your website and crawl through those memories from so long ago. I was the Jack Moyer you responded to in the advertisement and signed your original offer letter. Yes, NCR hated us and used to call Floyd Kvamme to tell us to stop hiring their people (especially the test floor which was virtually all ex-NCR) - Floyd would call me and I'd stop for a week or two then back at it. I still keep in touch with Bob Spencer from time to time and with Tim Harris who followed me to San Diego after I returned to Santa Clara for another HR role.
Great web page - thanks for the memories.
Thanks for the email. You really are a voice from my distant past.
As young engineers at NAS, we had a chance to work in an exciting industry. I'm amazed at how young everyone was (at the time).
For about 20 years after the layoff, we did a mini-reunion every January for anyone who worked at NAS. I'm still in touch with many of the engineers and technicans that I worked with.
May I use your email on my web page? I can leave your email address off or use a home email address if you prefer.
If you like, you can expound on your memories as well. It would be interesting to hear how HR operated to staff the company.

Feel free to use my email in your website.
HR was primarily recruitment focused during my time. I was transferred to Exsysco in November '76 and returned to Santa Clara for NSC in February of '79. We would grow from 50 to 1100 people during my time and zero to $100 million in revenue - a real wild ride. As you can imagine we were hiring at an unbelievable pace and totally focused on getting people on board. In early '77 HR was Debbie Watson and me - I added Terry Mick in late '77 and then grew to a total of 7 or so people by the time I went back to Santa Clara. Randy Bresee who was our controller after Mike Woodward left and I are still friends and often reflect on the hard work and great fun. We were all young, energetic and at a great time in our lives. We worked and played hard. There were organizational and performance issues, and our share of drama, but all in all the experience survived the test of time.
I forwarded your site to Bob Spencer and he is going to go through some of his old material and forward anything that is of additive value.
Thanks for the note back.

I think I remember you. I left Exsysco in 1978, but I stayed in touch with the people. That unknown Tech in your photographs is me. I worked with Paul Hastings, Bill O'Neal, Dennis Daniels, Buck Titherington et al in the back of the Digital Scientific building before it was sold (given) to Exsysco.
Here's what I looked like back then:
I talk to Buck Titherington once in awhile. He moved to Boston. I spoke to Hanan Potash a few times after he started his Cray clone type company with George Kenoshita. I also worked with Chuck Laustrup a couple years here at Intel in Oregon. He remembers working with all those guys too. Old Bob Hinkle shot a guy in a bar in Arizona. And crazy Bob Shows!

Thanks for your email. I'm not sure that I remember you. I started at EXSYSCO in May of 78.
Which group did you work for?
I got an email from Buck a year or so ago. I just added it to the web page. I still hear from Dyke Summers every once in awhile. I remember Bob Shows. I haven't heard the names Hanan Potash and George Kenoshita in 25 years.
After the layoff in 1983, we got together on the aniversary of the layoff. This happened for almost 20 years but we haven't had a reunion in a while.
A lot of the guys in Field Engineering ended up working for what remained of EXSYSCO which became Hatachi Data Systems so we saw them occasionally at the reunions.

I noticed I forgot to answer your question and I also noticed in my email that I had said "Brad" Daniels, I believe his name was Dennis. He was Manager of Field Service, Paul Hastings worked for him.
I worked for Stu Kroll and Bill O'Neal. I was a lowly Tech back then still going to San Diego State and UCSD. I joined Digital Scientific, Dave Ahlgren, et al on the Meta 4/370 project around Oct./Nov. 1975. I really enjoyed working in the back of Digital Scientific in a small group of only 5 or 10 people.
When we transitioned into Exsysco and moved to Roselle St. the company exploded to over 1000 people, and the fun was gone so I left in early 1978 just before you arrived, but I remember your name vividly, because a Stock Broker friend of mine was Michael DelVecchio and I remember telling him about you and how your names were so similar.
One other thing regarding that email. I recently retired from Intel, so you may want to put an (ret.) after my title. Here's a presentation http://bt.pa.msu.edu/TM/BocaRaton2006/talks/davis.pdf
I left for Michigan State, where I did my PhD work in high energy Particle Physics. We had just gotten 80 processors to run on a single die when I did this presentation in Boca Raton.(The Polaris project)

Subject: AS/6100 processor question (pics attached)
We enjoyed your website, lots of great computer history and photographs!
We are researching a piece of NAS AS/6100 computer memorabilia in our chip collection. It is a LGA ceramic processor we believe is from around 1982.
Was this type of processor made by Hitachi or Motorola? (picture of the item is attached). It looks similiar in style to some of our Amdahl air-cooled processors.
Thanks in advance for your help in identifying this processor, we want to make sure we get our description correct on our site.
The chip that you have does appear to one from the AS/6100 that I worked on in the early 1980's.
If you look on my web page for the AS/6100, you can see several photos of the chip. We mounted the chip on a daughter board.
The chip was a gate-array and was fabricated by Motorola using their MECL 10K Emitter Coupled Logic Circuitry.
I may have a data book from Motorola on the gate-array family.
for all the help identifying this as Motorola, now im wondering - why
wouldn't NAS use a chip manufactured by National Semiconductor?
Was it due to patents or did national semiconductor not have anything
like the MECL to offer it's NAS folks at the time?
Great hobby, learning alot from folks like yourself, I will defintely check out that data book...thanks for offering that to all to see...
Motorola was the only source for the high speed ECL circuitry. Signetics was a second source (I think they had a sourcing agreement with Motorola).
When you get the photos on your website, let me know and I will add a link to them from my web page.

Hey, long time no see! I found your website and I'm so jazzed to see all the familiar faces once again. I worked at NAS under Dave Adams, in CAD
as a 23 year old pcb designer, and also did gate array layout. Remember those 133x enlarged cell maps on mylar, and especially the 'beast' that I was
able to squeak by with the last 3 hook-ups - "The Mover"? I remember the bottle of champagne and t-shirt that engineering gave me for
completing it. I have so many great memories of working with great people there at NAS. That place at the time with that select group of
people was one in a million!
I'm working for Intel now outside of Portland, OR.
Wish you the best,

Subject: NAS website, memories
About 6 months ago I found your great NAS website. You did a fantastic job!
I worked there from July 1981-Layoff. My first job was in the memory dept. and later on the AS6100. It was an amazing experience, and at one point I actually believed the company would be around for a long time--an old fashioned job! Here are a few memories:
To prep for the AS6100, we had one INTENSE month of training on theory of ops and troubleshooting of the wirewrap predecessor. I remember dreaming about the logic diagrams. Do you have any in your book--the ones with gates rendered with ASCII symbols in rows and columns, all kind of looking the same? I'd love to see one of those on your site.
Before going to the system debug dept., I brought up the service processor and power system--lots and lots of Amperes! Occasionally exciting! The ID tag in your photo is 35A at 208V = 7KW+. As one of our trainers said, a bad programmer could turn it into a $500K room heater!
The great fire: In early 1982, 2 boardsets ($100K+) were destroyed by a burn-in chamber failure. One giant step backward.
Many of the devices were not layed out on std.on 1/10 in. centers, so automated testing was difficult. In the summer of '82, they used brute force and hired dozens of temps to ohm out every node connection. The defects were passed to techs to sort out due to the rework wires and cuts and drills! We spent hrs. looking through layers of artwork to track these down.
At one of our monthly meetings I asked why we didn't use National ICs (as did a previous poster on your site). They were right there in those beautiful data books--why not use "vertical integration"? The response was that our chips didn't meet engineering req'ts!
At these same meetings, there were charts that showed us losing money, but at a lesser rate than they anticipated, so it was o.k.!
National had a great stock program for the common worker. The only thing that really worked out--I bought in at $19 in 1982 and sold for $57 in May of 1983!
The first production units were very difficult to bring up--huge amount of rework on boards and backplanes, not always done right! It seemed like we were way behind. I recall the original clock speed goal was around 56nS, but ended 10-20% slower. Seemed like we were in trouble. I worked the 2nd shift (4 day week thing) and when I came to work on FCS day, from the view of the parking lot from the I-5 freeway ramp, I thought the crowd was there because of a layoff meeting! As soon as I saw the champagne glasses, I knew it couldn't be that. You might say, as a 2nd shifters we were kept in the dark. Once the boards were cleaned up, it went pretty smoothly, but little did I know that it was too late!
Right after I started in in the memory department, they started building Hitachi memories. The most striking difference was that they soldered the memory chips (vs. socket them for replacement, anticipating failures). Also, the poor smokers had to step outside.
Gary Griffin and Ken Davis were a great help in production. Later, I worked with Dyke Summers (Celerity Computing) and Chuck Stead (Overland Data). I still meet people who worked at NAS.
It was a privilege to be near the cutting edge so long ago--it gives me a perspective that makes the new developments in technology so mind blowing--the "youngsters" simply take it for granted!

I was forwarded your Exsysco site today and found it quite interesting. I doubt you remember me but I was in tech support at that time. I started with NSC in 1976 in Sunnyvale working with add-on memories for IBM mainframes in both engineering and then tech support and in 1980 moved down to San Diego when that function (along with only 4 or 5 of us) consolidated with the mainframe products over in Sorrento Valley.
I ended up working in tech support for AS-5s as well and ended up parallel scoping bugs on them for many people in the field. I also installed one of the handful of 6100 systems you mentioned. I can't remember the customer but it was in San Diego - I believe also in Sorrento Valley. I was in various building locations but one of them was in the same building where the 'Lightning' was being developed. One look at that system and the way they were developing it and the issues it had and I said 'no way it'll work' and of course they ended up cancelling that one. By then Hitachi had some very solid mainframe clones including in the 3033 class that Lightning was targeting. I remember the various layoffs including the first big one when the AS5 line was shut down and then again when they shut the Lightning project down. That building got mighty quiet after that.
The company transitioned to NAS and then HDS. As you can see from my email address I'm still at HDS - one of the long termers. Nowadays I head up a software development group but I remember the days of working with the IBM mainframes, add-on memories, AS5s, 6100, being in the same building as the Lightning (I didn't work with it), and then working with the Hitachi products - mainframes, storage, etc.
I forwarded your link to a few others who may remember those days - Leon Helms, Joe Richards, Ed McElearney, Hub Gayle, Dale Hoberg. Some of these people were in the field but worked on the AS5s. The guys I just mentioned are all still working at HDS with the exception of Leon who retired a couple of years ago after being in my group for quite a long time as a software developer. We're still in San Diego but have changed locations a few times and are no longer in Sorrento Valley - we're sort of northeast of there along I-15 in the Carmel Mountain area.
Again, I really enjoyed reading through your site - it brought back memories (no pun intended).
I should remember you as I probably knew you. In the years after the big layoff in 1983, I saw Leon and other HDS people at the reunions that we used to have every year. (I actually lived in Scripps Ranch, not too far from the HDS office that used to be there.)
Its certain that we just couldn't compete with Hitatchi.
May I use your email on the web page?
Sure - you can post it there if you want.
In thinking about it I guess I might be the last one still working for the company in San Diego who was also working for the company in the AS5 days. Kind of weird to think of it that way.
Btw - I heard back from Leon after forwarding your site to him. He forwarded it to Fred Kokaska but heard the sad news back from Fred's wife that Fred passed away last September. Fred was with NSC for a while after the factory shutdown and then went to Qualcomm and then I think to Sony Ericsson. He seemed to always be working on his go-fast airplane to make it go faster. For quite awhile he kept a propeller in a lab at work. He was quite an interesting guy.
|Dana added this:
I need to add a postscript to my message - in thinking about it some more I realized I didn't know when Ed Castro started so I asked him today. He said he started with Exsysco in 1978. I started with NSC in Sunnyvale (in the group doing add-on memories for IBM mainframes) in 1976 and transferred to San Diego in 1980 so I think both Ed and I are now the last people in San Diego who worked here as well in the AS5 days but Ed has me beat as far as the length of time in San Diego.
Somehow we both seem to have lighter colored hair than we had back then.

It's me Rich Pizzo (RMAP), I just found your NAS site. So cool! I haven't gone through it yet, But I will. What brought me to it was a search I was doing for a "10KMECL Trouble Shooting Guide self teach manual, that I did while there. I do not know how many the Publications Department printed, but a bunch were printed, handed out and circulated. I am trying to find one. I would love to have one, even if only a PDF copy.
I did some interesting things at NAS with diagnostics, using various analysis algorithms -and later accessing design files- to predict failing FRU probabilities....and expressed the analysis within an -AID- Analysis Indicator an AID looked like this ". . . . . . 6 . . . . 3 . . . . . 1 . . . . . . ." each dot represented a FRU and the numbers indicate the total number of diagnostic algorithm votes for that FRU.
The algorithms were rather interesting... because no one of them was perfect they made sense sometimes and did not make sense at other times..... but when all were aggregated together, They did pretty darned good identifying the FRU... It was a case of aggregated fuzzy logic.. A form of Expert System.
Later, after National closed down, -that was so sad- Tran and I developed this idea further at STC Computer Research Corporation to include accessing design files, . I really enjoyed working at National.. and later at STC CRC. The software Tran and I developed at STC CRC, identified many problems it the STC CRC prototype check out.
I loved doing that kind of work.....
I am sad to hear about Fred and Buck's passing. We are all getting older. I will be 70 next year. I am wondering about Dyke Summers, I very much enjoyed working for him and with all you folks..
Good to hear from you after all these years.
I never saw the manual that you are trying to find. Sorry.
As far as I know, Dyke Summers is still living in San Diego. I don't have an email address. You could try emailing some of the other guys whose email addresses are on the page. If you get an address, let me know.

After the factory shutdown, most, if not all documentation was packed up and delivered to NSC for archiving.
Nothing was left at the Roselle street facility with the exception of some of the AS/5 documentation we needed for support.
I remember taking the AS/5 course for CPU troubleshooting and using various 10K ECL documents to understand the functions of all the chips used in the processor.
Sorry to say that I do not have access to any of the archives from NAS any more.
After NAS, we became HDS, Hitachi Data Systems, the joint venture between Hitachi and EDS.
Eventually Hitachi bought out EDS's share and we became a fully owned subsidiary.
Today we continue under the 'Hitachi Data Systems' formal name.
We no longer market IBM compatible processors but continue to market and support Enterprise Disk Arrays.
I am one of the very few remaining employees in our San Diego facility with Exsysco/NSC-LCS/NAS ties.
Dana Gillis is still here as well..

I started working there in 1977 just after getting out of the Navy. I was on the main floor (technician) and spent about 2.5 years there until the layoff started. We just got in an IBM 3033 to reverse engineer and shortly after that the company went under. I got transferred to DataChecker ( another division of National Semiconductor) in Tampa, Florida and about three weeks there I got a strange call from my boss asking me to go down to one of the banks and see if I could repair their mainframe. The tech had been onsite for over 4 hours and California was standing by to fly in David (one of the engineers) to Tampa. So I talked to him on the phone. His first comment was 'what the hell you doing in Tampa"? I told him I moved here and then asked him to let me get to work since I had not looked at the problem yet. It was failing an H disk routine and after about 15 minutes I replaced a SIP and the machine was up and running. Then ITEL down in Miami tried to hire me and I stayed where I was. I worked for Stu Kroll and Bill O'Neal on both the first and second shifts. A lot of the time I worked on Saturday and Sunday. Was young and needed the money. Left National Semiconductor and worked for NASA for eight years as an engineer at the Marshall Space Flight Center. Started my own corporation in 1998 and am somewhat retired now.
I don't know if you remember a guy name Jack Peters who was killed in a motorcycle accident, but we were supposed to be renting an apartment together. There was also one guy Coleman (David I believe) long brown hair and looked like jesus. Barbara Reeves also worked there.

Thanks for your email about NAS. My web page dredges up someone every couple of years.
Good story about the computer in Tampa. You saved the day. I suppose that was an AS-5.
I don't remember you but I do remember Stu and Bill. Stu ended up working with me in Engineering when the division finally closed down.
We were all young and worked way too much. But that is what you do when you are young.
I don't recall the names Jack Peters or Dave Coleman either. But I do remember several hirsute test floor techs.
Can you put your email on my web page? Might be of interest some of our former co-workers.

I just remembered it was Dennis Coleman and one of my good friend I stay in touch with is Sherry Coleman (they are not related). She worked on the morning shift with either Bill or Stu and got hurt. I was on workers comp for about 10 weeks when I stepped off the raised floor onto an IO cable (bus and tag) and broke my left foot in five places. Hopped over to Bill and he looked at me and goes 'Shit what did you do?" Not sure if you were on the fishing boat for one outing, but Jack hooked me with a fish hook in the leg and I found out who had the booze and drugs that day. I worked on machine 100 and we all signed the inside of the door. I was part of the second round of layoffs in 1979. Those machines, wired wrapped and all, were pretty amazing. Remember the add on memory unit and the XAR? One small wire enabled the executable array. Had to go to a client one day and Bill told me to make it look hard when I had to enable it. Right. Less than 1 minute and I was done. Also went to the Christmas parties they use to have.
There was a little place about two block away we all went to eat from work.
How do I add to your web page? I will put a lot of info on that someone may remember.
If you send me emails with your stories, I will make sure that they get on the web page.
|Was cleaning out some
old boxes and found one of the 8" floppy disks used for testing.
I think it is the H disk. Also found an old pay stub dated
6-10-79 with EXSYSCO on it. Somewhere in this house I know I have
an old tape from there and some programs we made to test memory and
some other stuff. One tape had STS370 on it that was
a program we ran in the final test phase I think.

Hello, I worked at Exsyco on the test floor then moved to supporting the test floor system programs and in the national support center for VM.
I found my name in the phone book, Matthews, Jim Ext 367 Bldg 4 M/S 9.
When I went on the interview at Exsysco everybody in the room were people I knew from NCR.
Eisenhauer, David Ext 496 Bldg 4 M/S 9 was my manager and when he moved to Dallas, Tx, to setup a support center for Four Phase in 1981, he asked me to join him. I joined him in Dallas on Jan 4, 1982 after graduating from college with my Programming degree.
I remember when we were in line to turn in our Exsysco badges and get our NAS badges, the guy in front of me, refused his badge since it said Bob instead of Robert! I do not remember his last name, but he moved to Dallas, Tx, also.
When I was still on the test floor, I came into work and was told to go to the loading dock. I asked why and he said just be happy you are going to the loading dock. The people who went to the cafeteria were laid off.
I worked second shift on the test floor and in 1980 I switched over to supporting the programs on the test floor from midnight to noon.
The problem that gave us the most trouble were pieces of solder, little balls, that would move around when you were trying to trouble shoot the problem. When we finally figured out the problem, we would sent the panel back to have the wiring removed and rewired. After a while we figured out that they were not rewiring the panels, so we started tracking the serial numbers. When a back panel showed up with the same type of problem and serial number, it would be ACCIDENTLY dropped and broken.
When I was supporting programs on the test floor and VM/SP in the support center, I called over to operations to have them mount a disk drive for me. After a while, I called back because the disk had not been mounted. She said the disk was mounted. I asked her to doubled check and she said it was mounted. I went over to the operations center and there was the disk setting
on TOP of the disk drive. She thought it was mounted because it was setting on top of the drive..

Thank you for the page you put up about the Large Business Computers division of National Semiconductor. I was there in 1979. I started in the R&D lab working for Al Casper. I and a guy named Bill built the APU prototype that worked the first time it was fired up! All I remember was that there were a ton of fabric cables interconnecting a butt load of wired boards.
As a reward, John Conti, offered me a drafting position where I worked with a wonderful Vietnamese fellow named Ton Bui. I remember having a lot of interface with Bev. Sorry to hear he passed. He was an exceptional man.
It was one of the best places that I ever worked. Everyone was laid back and doing what they enjoyed, but we always seemed to get the work done.
Thanks for the memories.

Long time, no talk! I stumbled upon your nice history piece on Exsysco. I also worked there first for Tim Brehm on the Multi-Processor Attached-Processor system. I designed the interprocessor switch including memory switch, cache coherency, etc. and also designed the 4 Megabyte (ha ha ha!) memory box which I remember as about 4' x 3' by 5'. The memory cost $75,000 per megabyte as I remember. I then went on to be the first engineer on the Lightning project where I did the first architectural logic organization and design translation for the project. I think I worked for Howard Sachs but I can't remember if he was the one in charge of Lightning. Thanks from all of us for doing such a nice job on the Exsysco history!
A lot of water has gone under the bridge since we talked last, too much for one email. I worked at Megatek on the Sigma 70 and then went to Ball Aerospace when Ball bought the Sigma70. We did a lot of flight simulator math engine accelerators at Ball. After my stint in Minnesota at Control Data Supercomputers. I went on to do a couple of small projects designing mathematics sets and architectures for specific high-speed number cruncher applications. Now I am at Cybortronics where I do Phase Change cooling systems and electronic/electrical design for environmental test chambers. Our customers include Cisco, Western Digital, Jabil, Foxconn, etc..
I do remember doing some design work for you. I cant remember your partner's name. The job was for Dr. Design as I remember.
Its nice to remember the good old days and all the cool people that we worked with for all those years. RIP Buck Titherington.
Lets get together sometime for lunch and catch up.
Sr. Staff Engineer
Ah! A voice from the past. I remember you and the memory boxes that Exsysco/NAS did. Geeesh, I threw out a gigbyte memory that cost me a couple of dollars yesterday.
Those where the days when we worked really hard and had a lot of fun although many of the products never saw the light of day - like the NAS AS-6100.
Doctory Design (run by Marco Thompson) was bought out many years ago but he is still running around San Diego. Megatek, as you probably know, is long gone.
There is another guy from EXSYSCO that you may remember, Randy Parrish. He was in the Attached Processor group. I am planning on directing him to your NAS site, I'm sure he'll get a kick out of it. Also, we must remember another member of our group, Ellen Maskell, who was tragically killed in a car wreck right on Sorrento Valley Road, or thereabouts, by the old NAS plant.
I think I read that you are retired now. I am 59 and still cranking full speed, I'm planning on backing off a bit on the workload soon and retiring at 66 unless I win the lottery. Cybortronics is a nice little company to work for and will probably be my last employer before retiring unless something happens that changes my plans.
I was reading some of the info in your NAS site about the demise of the Plug Compatible Mainframe industry. At the time, someone at NAS described the demise of NAS and the other PCM companies to me in a way ill never forget. He said that IBM was very smart in the way they got rid of those pesky PCM companies: The story was something like this: For a mainframe computer IBM would sell the hardware for $750 K and the software for $250 K. This allowed NAS to come in and undercut their hardware by selling NAS mainframes at something less than $750 K like $500-600 K. In order to wipe out NAS and other PCM companies in one easy move, IBM simply changed the pricing on a mainframe to $250 K hardware and $750 K software. Checkmate without even breaking a sweat.
Have a good one,
I looked at the November 1979 NAS/Exsysco phone list and did not find Ellen (or you for that matter).
The last name on the list was Sandor Zoboki who was later written up in this article:
Yes on including my emails. I would be honored to be included amongst our colleagues on your NAS page. I am not sure why neither Ellen or myself are in the phone list. I read the thing on Sandor. I remember him and his VERY colorful past. He was a cool guy as I remember.
Speaking of colorful past. I just remembered a guy named Stan Rifkin who worked at NAS if I'm not mistaken. One day Stan didn't show up for work and if you google his name, you will find a number of articles on why. I won't go into detail here...
Ill be getting ahold of Randy Parrish later this week when I get a moment, Im sure hell want to get in touch with you. Im not good with dates... I left NAS when the Lightning program was scrapped if I remember correctly. I wasn't involved in the layoff. I don't remember when Randy left.
As I think back, EXSYSCO/NAS was really a great pool of high-end computer people. The atmosphere was great and the machines were fun. The people at EXSYSCO/NAS remind me a lot of the engineers at CDC Supercomputers/Star Technologies in Minnesota. There were a lot of high-end computer engineers in Minnesota working at the various supercomputer companies. There was a Mensa Supercomputer sub-group that was pretty wild.
Have a good one.
