Univac 8008 microcomputer
Craig Solomonson and I had our first correspondence 20 years ago when he offered me one of his Apple-1 computers. I did not purchase that one and it sold recently to Marco Boglione for  $216,000. Craig bought that one from the original owner in Great Falls, Montana and later sold it to a collector in California for $25,000. He in turn sold it on eBay for $50,000 and then it went to Italy.

The Univac 8008 computer Craig has is rare and is most likely the only one in any collection. 

Here are some of Craig's comments about the Univac 8008.

David, we corresponded a bit a few years ago about an early Intel SIM8-01 micro system that I had. It seemed to be a relative to your MCB8-10 system. Well, I finally found out the story behind my system….

Univac 8008 microcomputer
It was built by the Univac R&D Division in St. Paul, Minnesota in 1972. They were carefully monitoring the developments at Intel with regard to their 4004 and 8008 microprocessors being developed. Part of their research was to construct actual computer systems to research and then build an application using the 8008. They started by building a 4-bit system similar to the one I have using the SIM4-01 and MP7-01 boards. That unit was completed and being demonstrated by March of 1972. They ordered the 8-bit system (SIM8-01 and MP7-02) when it was announced in April of 1972 and construction took place during the summer of 1972. Univac designed and built their own interfaces for these systems and used a Teletype for I/O. The Univac 8008 "8-Bit Micro Computer System" in my collection was complete and being demonstrated to various Univac divisions and military organizations by early fall of 1972.

Bugbook Historical Microcomputer Museum
I visited with one of the Univac engineers that did some of the programming and he said that only very simple programs were used in demonstrations--like doing simple math operations or it asked for your name, you typed it in on the teletype and it printed some phrase using your name.

Univac spared no expense in developing this system as seen in the construction and fabrication of the cases which are thick, deep red translucent plastic. Not only is it a very aesthetically designed, but it has to be one of the very first 8-bit computers fully assembled and operational. 



Univac 8008 microcomputer
That system has always fascinated me and I figured it had to be one of the earliest 8-bit systems ever assembled. I have gone through several boxes of Univac Engineer log books in the Charles Babbage Institute archives, but so far have not found a log book for the development of this computer. I know that Univac ordered the boards as soon as they were announced and the SIM8-01 board in the computer is a very early one. I also know that it was done and being programmed in the fall of 1972. However, that engineer could not remember when it was actually completed. I think that the engineer who did the actual design and circuitry for the interface is still alive and living in Minnesota, but he will not respond to phone calls or emails. Hopefully I will find another engineer on the project that might remember more details and hopefully dates.

More interesting information:
A video Craig made this month about his collection and the 

1972 Univac 8008 Micro Computer System - One of the First 8-Bit Computers!

 Craig comments "I have a modest collection of early micros and they are shown on my website."

David Larsen
 I was very glad to hear from Craig about his Univac 8008 computer. I saw a photo of his 8008 computer several years ago and asked him about it at that time. Now he has a good idea about the origin and the very interesting history about the computer. These very first microcomputer systems are important to preserve and make known to the interested public. 

Thank you - Craig for sharing this information and I hope the blog will help inform people about your unique vintage Univac.

Bryan C. Dowd amateur radio operator KG4ZKA is a big help as assistant student curator in our museum. Bryan has an interest in computers & history and these vintage computers are fun for him work with. He welcomes visitors and gives them a full tour of our museum and helps them with our active vintage gaming stations. We have several Commodore 64's and other vintage games.

We have a PDP-11 minicomputer - next to Bryan - The minicomputer is used (cost as much as a house in early 70's) to tell why there was such an interest the low first cost microcomputers like the MITS Altair 8800 (January 1975).  When Ed Roberts put his Altair on the market in January 1975 he told the banker 500 sales were likely. The demand for his simple $400 Altair exceded 4000 in a few months.

A different view of the museum from the other side of the PDP - 11 minicomputer. Just to the left of Bryan is an ASR 33 teletype and this is always of interest. I don't remember what these sold for in those days but it seems like it was about $2000 - Just today hp printers were on sale for $59.  So many stories and comparisons to tell our visitor about --- where & when the microcomputer revolution compared to today. Moore's Law continues to work just fine with technology leaping ahead at warp speed.

Soviet Flag
My wife and I were fortunate to travel in the old Soviet Union before it broke up in mid 1991.These visits were for two purposes - To teach about computer automation to deliver donated computers to people in Russia and Ukraine. We were able to obtain both Ukraine and
Russian amateur radio license's and operated Ham Radio with contacts made from Lviv, Ukraine, and Moscow & Ulyanovsk, Russia.  We were representing "Virginia Tech" (VT) for teaching and "The Foundation For Amateur International Radio Service" (FAIRS) for the radio activities.We had to get approval from the US Department of State for all our computer teaching and donating computers. That was an interesting exercise with lots of forms -- it did work out just fine and we made 20 or so more visits after the breakup of the Soviet Union.

The president of Ulyanovsk Polytechnic Institute (UPI) "Vladimir Efimov" gave me this computer during our first visit when we signed an exchange agreement with his Institute and Virginia Tech.  This exchange agreement resulted in a number of faculty visits between VT and UPI. Valdimir made one of these trips with some of his faculty members and not only visited VT but they all came out to our house for dinner one evening.

Here is the bottom view with the IC's showing. I did not know much about this computer however when I posted the video Ed S send a message that this is a clone. Here is his information

Ed S- It's a Delta-S (Дельта-С) a Spectrum clone - the multi-function keys are characteristic of the Spectrum keyboard. In this case there's an additional mapping, of Cyrillic characters. Therefore not precisely a clone, but an adaptation. Some photos:

More activities during this visit. 
This visit lasted 3 weeks and our group carried about 50 personal computers to donate to the Soviet people.

I wrote a letter to Soviet President Gorbachev in November 1990 ( this was about 6 months before this visit). I did not know if this would help however it opened many doors for us with response from various parts of the Soviet Politburo.

With Soviet President Gorbachev putting out the word to help our group we were treated very well in all efforts during this visit.








If you made it this far you have a lot of patience and here is a summery of the trip. 

David KK4WW and Gaynell KK4WWW Larsen make their second visit to the former Soviet Union. This time additional travelers join them  they include John Douglas N0ISL, Bob Friebershauser W6YMR and his wife Virginia.  The group visited Lviv  Ukraine and Ulyanovsk Russia. Computer workshops were taught in both locations and many amateur radio contacts were also made from Ukraine and Russia. This trip also included a visit to the well known "Box 88" Krinkle Central Radio Club in Moscow.  Box 88 and the club vanished after the break up of the USSR just 3 months after our visit.

W6YMR and N0ISL are now silent keys ( passed to the other side)


Here is a podcast recording with comments by David and Gaynell Larsen about visit that was so exciting and interesting for us. We still talk about this visit 25 years later,

Bangladesh Ambassador to China - Left
Dinner at the Embassy in China ! 1995 
Here is the Bangladesh Ambassador and his wife to China in the Beijing Embassy. I sure wish I had made more photos. We had dinner with these two and my wife at the embassy. The dining room the table was about 40 feet long and could have seated at least 100 folks. The four of us just used a a little part at one end. The food was some good Asian with lots of curry.

We were in China with 19 students from Virginia Tech visiting for about 4 weeks. This was a great trip and we put on several thousand miles from North to South in China.

Our meeting and dinner lasted about 3 hours and the conversation with the Ambassador and his wife was just great. Beijing was our first stop during our China visit and the ambassador gave us a great understanding  about the  current China.

The Students traveling with us had no idea where we went for dinner. Returning to our hotel it was useless to tell them "Oh we just had dinner over at the Bangladesh Embassy with the Ambassador and his wife" of course they did not believe a word of it. We did not have digital camera's to tell the instant story in those days.

This was one of those WOW moments and my wife and I still talk about what a great experience we had.

How computers and ham radio made this trip possible - My ham radio  and work with computers & scientific instrumentation made my faculty position at at Virginia Tech a reality. The trip to China was a Virginia Tech (VT) venture put together by VT Professor Jim Littlefield. My wife and I joined his group for the visit to China.

---------------------------------------------------------------

Here is a bit of my history that made the meeting and dinner with the Ambassador in Beijing a reality!

Amateur Radio began for me in 1954 at 15 years old with the call W7VZW.  A few years later in 1957 at 19 years old the Navy sent me to school at "Remington Rand Univac" to be a technician on a
very large secret computer  project at the War College in Norfolk, VA. The only reason I received this opportunity was I was a Ham Radio fellow with an excellent knowledge of electronics. Only about 12  in the whole Navy were part of this project as technicians.

Years later in 1992 I arranged an Amateur Radio  DXpedition to Dhaka, Bangladesh with the help of Dr. Toufiq Ali the Deputy Chief of Mission at the Bangladesh Embassy in Washington DC.  Over the next few years Toufiq and I became very good friends and one day I mentioned to him our planned trip to China. His reply was "Oh that is great I will call my friend who is the Bangladesh Ambassador in Beijing and have you meet him".  I thanked Tofig but really did not take it to seriously --- however when my wife and I arrived in Beijing I called the Ambassador and indeed he said " Oh Tofig told me you would call can you come over to the Embassy for dinner" . WOW that got my interest real fast and plans were made for that night.

This computer experience started a long and wonderful career for me and it is still getting better at 76 years. 
Ham radio experience and learning was good  enough to get me to school at Remington Rand Univac. I was just a kid in 1957 - 19 years old and just graduated from high school.  This was my first experience with computers.

I was also honored to give a lecture to about 200 students at Tsinghua University  about the international advantages of amateur radio. That was exciting.




-----------------------------------------------------------------------------------------------------------
Why write about these adventures ?  I want young people to know not to limit your thinking and about the opportunities than you can create for yourself. Every skill you have like HAM RADIO can open many doors to great adventure.

Here is just a few more adventure my wife and I had the pleasure of enjoying.

-- Visit to Guyana South America at the personal invitation of  Dr. Cheddi Jagan the President of Guyana. We even lived in his guest house during our first visit. I will write about this adventure as it also included computers and amateur radio.

---President George Bush 41 and his State Department Staff helped in many ways with our visits to the Soviet Union in the 90's. We even received a $25,000 grant from the US Department of International Aid (USAID) to help with out Soviet Work. Check out this adventure "CLICK"

----We operated amateur radio from the Bangladesh and Guyana Embassies in Washington D C as a result of our contact with the officials from these countries. We are still good friends with Peter Denny in Guyana 8R1WD ( Peter was the Guyana Ambassador to  Russia for 7 years in the 90's & in China one year) and have radio contact 3 times a week. Peter arranged for our operation in the Guyana embassy in Washington DC many years ago.

--- The list of great and exciting adventures during my 76 years have been more than I could ever imagine -- just great and they have not ended yet. Take a look at one more in Soviet Union a video.

Jon Titus - Computer Pioneer comments about 3 of his mentors

Bugbook Historical Microcomputer Museum
Jon Titus

(From Design News November 2013During my several careers I had the good fortune to learn from three mentors, and as I wrap up my career, they deserve mention. I hope you have had equally good fortune to work for and with such good people.

"When I got to grad school, I met David Larsen, who taught an 'electronics for scientists' class at Virginia Tech. We hit it off right away, and a few years later Dave helped several of us start a company that created educational electronic hardware and books for people interested in computers and electronics. Dave showed us new ways to approach business, gave us encouragement, and suggested helpful marketing ideas. I learned a lot about how to work with people, how to communicate well, how to conduct business fairly, and how to carefully evaluate business opportunities. He might not realize how much I learned from him and how I still enjoy our friendship. Now Dave promotes amateur radio for personal and emergency communications in the Republic of Dominica through his FAIRS charity based in Floyd, Virginia."

The other two mentors Jon mention as his good fortune to work with are his eighth grade science with John Shuttleworth & Roy Forsberg was the editorial director of EDN magazine.

Read the entire editorial Jon wrote as his  last in a long series of columns for Design News at retirement in November 2013.  The information above  is quoted directly from the editorial in Design News 11/27/2013.


------------------------------------------------------------------------------------------------------------------------------------

I have always had a great respect for Jon Titus and the 10 years we worked together in the "Blacksburg Group" were some the most rewarding during my 31 year career as a faculty member at Virginia Tech. Thank you Jon - for the friendship and wonderful memories - Dave Larsen

Jon's contribution's to the Blacksburg Group were many and I have written about some of them here in my blog. A few of his contributions are ....

I  retired from Virginia Tech 17 years ago as a faculty member in the Chemistry Department - it  seems like it was yesterday. I have many fond memories of jobs, projects, family and friends. It has been said  you can't look back but that seems simplistic to me - my computer museum is all about looking at the past - .  at 76 I don't think old and fortunately I don't even feel old - the past memories keep me looking forward and wondering what interesting and fun thing will be next. For sure this Christmas with my wife, children, grandkids & great grandkids gathering at our house was just wonderful.  I counted 28 for dinner last Friday and still today at least 6  in the house today 4 days after Christmas. WOW!!!

Ron Wayne, Apple co-founder
Ron Wayne owned 10% of  the Apple Computer Company (April 1,1976) and was co -founder with Steve Jobs & Steve Wozniak.  Ron contributed his business & engineering skills however when the Apple needed to borrow money to build the first 50 Apple-1 computers he did not feel comfortable with his part of the debt responsibility.  Ron Sold his interest in the Apple partnership for about $800 only 12 days after the formation of the partnership.  Ron  was a creative designer and continued his design work after selling his interest including the original Apple logo and schematic  drawings for Apple.

The story of Ron's involvement in  Apple Computer is not well known however their have been some interesting turns of fortune for him.  The 10 % ownership Ron had for 11 days would now be worth about $30 Billion - that is with a B.

Ron was the business guy for Apple and wrote the original partnership agreement between Steve Jobs, Steve Wozniak and himself.  Copiers were not common then and 3 original copies with all 3 signatures were made.  Ron kept his copy of the contract  in a personal file for years and sold it  in the 90's to a signature collector for $500. That same contract sold December 13th, 2011 for $1.6 million to Eduardo Cisneros at a Sotheby’s auction in New York.
