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 used some smaller Intel 8008 boards in 1976 for a project,
but they generally looked a good deal like the ones in
the video, just a bit smaller. My guess is that is a
one-of-a-kind unit.

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!

What about security? Does Rpi employ a firewall and virus scanning? And since the pi uses sd storage, it might make more sense to compare it's internet capabilities with a tablet or smart phone.

Just last year, I had to show a young Engineer in my office how to use
my 1983-vintage Radio Shack scientific calculator! :P
He's young enough to either have mostly used smart phone apps for such
things rather than *real* calculators, or he'd forgotten how to use a
scientific calculator because of his app use/dependence.
Of course, another Engineer in my office discovered the hard way that
his calculator app was faulty when calculating a trig function (Sine,
I think) for a problem. Fortunately, a real calculator convinced him
that his app had a bug (a RAD to DEG conversion programming error) --
he immediately found a better calculator app.

Are said xsistors readily replaceable with one that can handle a wider range? What ultimately happens if you push a flyback too far? Burnt winding?

The only logic probe I ever owned, still own I think, was only good to 1mhz I think. Probably suitable for what you mentioned, but not everything on a pc obviously. Address and data is pulsed at what frequency?

Maybe not for recording Win7, but for learning BASIC, this
turns out to be good advice. One from Cindy's warehouse (after taking
off the dusty top case and washing it and the keys, and buying an
RCA-to-"F"-connector adaptor for the video) has spent part of last
night and *all* of this morning (since before I got up until after
noon) teaching Extended Color Basic to my 12-year-old son.
WOOT.
Maybe I'm dreaming, but I may finally have found at least a partial
antidote to "MineCraft".
Fortunately, I already own a cassette recorder and cable and the
EDTASM cartridge, and Drivewire 3 with OS-9 images runs on our G3
iMac, so assuming that talks to the CoCo, he's got room to grow for a
while. I suppose I should try to get Drivewire 4 running on the iMac
...

The talk about the Acorn and RISC OS reminds me that I've been
interested in one of these, primarily to run RISC OS. What is the
recommended version, price, and place to get a Raspberry Pi from?
I assume I want a "2.0 Model B 512Mb"? I've found a seller on eBay
with this and they include a case for $57.

The first half dozen or so versions of AutoCAD could run at CGA resolution. I ran my first version of AutoCAD (2.08, Release 5) on an XT clone with a CGA card. Later, I was able to afford a Techmar Graphics Master. I could run that at 708 by 708 monochrome on the same XT clone. I still have the software, but unfortunately no longer have the Techmar card. I have also run AutoCAD 2.14 (Release 6) on an HP 200LX palmtop, which is basically CGA. It can be done, but the limited resolution does hamper what you can do.
I also have a copy of AutoCAD 1.4 (Release 4, 1983) that was customized by John Walker to run on an Otrona Attache 8:16 for an archaeologist colleague at the University of Chicago. The Otrona has a strange software emulation of CGA!

Better yet, let's test the premise in a non anachronistic real world way by transferring Winders 7 to o roughly 126,000 cassette tapes. You can start w/o me. I'll join in in about 6 months.
My advice is to get the fastest 8088 you can find.
