Engineering Introduction, Chapter 40

In addition to enginering computers and systems; in order to field practical, reliable operational systems; we also developed and delivered many peripheral devices and communications equipments. We supported these in the field. Our programmers and engineers developed test, support, and operational software. Our equipments were assigned UNIVAC/Sperry type numbers and in most cases a military nomenclature - A summary card is available.

2. History tidbits from Frank Kline

  I had a small ERA engineering group doing circuit design but there is little paper trail available.
  Adi Khambata worked for me and did original work on integrated circuits working with people at T.I., Motorola, and Fairchild.  Adi wrote the first book on Integrated circuits and it was printed for UNIVAC marketing and given to people all over the government. Adi also was the first one I know who published a book using a computer and submitted the text to the publisher on floppy disk. Adi was in charge of a radiation lab reporting to me where he directed tests on simulated nuclear weapon effects or radiation hardness design of computer circuits. The lab used a flash x-ray in a shielded screen room to test integrated circuits. We were among the first to work on radiation effects. Much of the work in those days was sponsored by Internal Research and Development and reported to the government.

   Lenard Corkey Pollick was responsible for the ERA bore hole camera project under Howard Daniels. Corkey was a physicist and made all the optics for many of our projects.  Frank Kline

3. Design and Drafting of Printed Circuit Boards by Bob Langer

Where would a computer company be without a key ingredient for its success such as the Printed Circuit Board (PCB)? Of course it would not exist. The design of the PCB artwork patterns, the supporting documentation and the tooling used to manufacture and assemble PCB’s must be cost effective, very accurate and with fast turnaround.
I was hired in 1957 by Remington Rand Univac and retired in 2001 with the same company now called Lockheed Martin. I was in the same Design and Drafting organization for my entire career of nearly 44 years. This includes two years of military leave in the U.S. Navy aboard the very popular tourist attraction the U.S.S. Intrepid, a WWII aircraft carrier, which currently rests in a New York City harbor as a museum. It attracts over 750,000 visitors annually.
My educational background was one year at the University of Wisconsin River Falls in a pre-engineering course prior to employment and during employment I received a Certificate of Completion in Electronics after 3 years of night classes at St Paul Vo-Tech.
     My career started as a draftsman working primarily with the design of PCB artwork patterns from circuit sketches designed by electrical engineers. In the early days we used black masking tape 1/8” wide and 3/8” round donuts or pads to create the circuit pattern for the artwork at a scale of 4:1 which would be photo reduced to 1:1 by the factory. That artwork photo tooling was used to etch the circuit pattern on copper clad board material. I would estimate hundreds of artwork patterns for many projects were developed by our PC Design Group for fabrication and assembly by our own factory during my career.
     A very significant advance in the development of PCB artwork patterns came with the new age of drafting automation called Computer Aided Design (CAD.) In the 1970’s Earl Vraa’s Software Group developed the software capability for drafting to input the electrical engineer’s schematic sketch into our company mainframe computers to automatically route circuit lines and generate artwork patterns for multilayer PCB’s. It also provided associated schematic and related drawings to fabricate and assemble circuit cards. I always felt this software provided our company a very competitive edge giving us the advantage over other computer companies to win major defense contracts such as AN/UYK-43 and other major projects. At that time I was responsible for the PC Design Group that did all the artwork designs and documentation for our Defense Systems organization. I would venture to say the peak workload for our group came in the1980’s during the design and development of projects for AN/UYK-43 and AN/UYK-44 computers. This was also the startup of integrated circuit design and development within the PC Design Group. I was responsible for 55 people in this new PC/IC Design Group including the photo lab area which produced the glass plate tooling and provided coordination with manufacturing. The IC Design portion of the group separated to become part of the new semiconductor facility during this period. In the 1990’s the PC Design Group started using personal computers with proven vendor supplied PC design software required for the very complex PC designs. These new designs using complex integrated circuits significantly reduced the overall quantities of circuit cards needed for a project causing a reduction in drafting personnel, the closing of our manufacturing facility and was my time to retire.
     Overall I had a real interesting career experience going from a manual operation with a large number of great hard working people to a totally automated group requiring only a few highly skilled PC Designers using outside vendors for manufacture. I still meet monthly for lunch discussions with the retired designers and engineers and enjoy playing golf with them quite regularly. Bob Langer

5. Embedded Processing and Communications by Harry Wise

The up grade to the 69B display system, this buried a PC in the old box. The PC was designed under Tom Ericson. It was the first PC design using the new “Topcat” chipset. Today every PC uses a chipset but I think this was the industry first. We tried to sell it to the Unisys Framington operation that was building a PC for the military. They paid a heavy royalty for a motherboard design from a Japanese firm on every system and lost money like mad. It was a poor design and expensive to build. We said that we would re-layout our mother board to industry standard format and deliver three prototypes for $50,000. [I think we said 3 months.] This would have saved $29,000,000. [I said that they were losing money like mad] Framington wanted to do it themselves. They shut the plant before they ever produced a revised motherboard. The company that we outsourced the BIOS design to used our design and built a business on it for years. I never could document this.

We did a whole series of communications devices. See Joe Pobiel. This was automating “transmitter farms” and “receiver farms”. The full system would have made significant yearly saving in man power in staffing these operations.

One thing we did was to build a remote control unit for the FRT-84 10 KW transmitter. We built over 260 of these. The original design had a remote control unit that did not work. Harris did a redesign that worked but when it failed it cost $30,000 to send it to the factory for a rebuild. These were both “10 U” high and full depth in a 19” relay rack. I had one small board with a Z 80 single chip computer. The bid was $750 per unit which was thought to be impossible. The final figure was about $350. I outsourced the whole build. We did several similar programs including a complete audio and digital switch. “A PBX with the wrong software.” [Harry Wise]

6.0 Computer Aided Design (CAD)

In response to a 2007 request from the Legacy Committee, Earl Vraa put together a summary of our company's history of Computer Aided Design. He had inputs from many other individuals who were developers of Automated Design systems software. He references three previous topical papers as supplemental sources:

We've posted these three papers as 'Article for the Month'. This CAD history isn't a complete story yet - there are some 'holes' as memories of the developers have waned. We welcome readers comments and inputs for a follow-up paper. One supplement already here are the experiences of Michael Pluimer - http://vipclubmn.org/Software.html#Simulations. [LABenson]

Now, in 2022 Earl Vraa and Jim Andrews are collaborating on yet another CAD history initiative. For example the Autogram Display and the role it played in the development of the 1110 computer systems.
