In the early 1980's I picked up a micro built around an Intel SIM8-01
development system at an electronics swap meet in Minneapolis. The
enclosure is professionally fabricated in a deep red translucent plastic
case and uses what appears to be one of the earliest SIM boards issued by
Intel. All indications is that it was built in the summer or early fall of
1972. I would like to find out who or what company might have built this
system and for what reason. I have posted a YouTube video showing some of
the features of this computer and a bit of history about it.
You can view the video at: https://www.youtube.com/watch?v=GG6goCIWCYY
What is also interesting is that the guy that sold me this computer had 3
micros on his table and all were like new and in working condition. They
included this Intel system, an Altair 8800 (factory assembled with serial
#5!), and a beautiful SOL-20. That was a nice little collection for one
individual to have at that time--seems like he was either well connected
in the industry at that time or might have been part of some local R&D
department (CDC, Univac, or Honeywell?) and was helping them clean house!
Let me know if you have ideas or have seen this system before. Thanks!

Hi I have one of the SIM4s with the programmer card.The 1702, 1701, 1602, and 1601 all
came out at thesame time. They were combinations of open collectoroutputs and latched
address inputs.The 1702 was the only one to be popular enough to stay inproduction.The
code on your 8008 is most likely code to run the programmerand a few other things. On my
4004, there are 3 EPROMswith the code in them.The input is not likely RS232 but 20 mil
current loop.It would have taken BNF data for the EPROM code.It is possible that your
system was actually built for Intelas a sales tool.It would be fun to recover the data
from your EPROMsMy set of EPROMs has the code to program 1702As.There would have been
slight changes to do the 1702s.Mine is operational and I've used it to read 1702s and
alsoto program 1702s. I made a simple 20 ma to RS232 interfaceso that I could use my lap
top to transfer data.I read the Sac State EPROMs for Druce Dommer withthis.It is also
possible that it was put together significantlyafter the boards were built as a way to
display thesehistoric computer boards.The additional EPROMs were added as collector
itemsover time and not likely to contain meaningful code.This also supports the idea that
it was built some timelater, rather than at the same time as the boards werebuilt by
Intel.It is a cool system, though.Dwight

Cool systems!
I'd bet this was used for demonstration / teaching purposes. And the
missing "manufacturer label" you point out looks just like one of the
tags companies or Universities use for inventory control ..
