Can anyone direct me to resources for documents regarding this piece
of equipment (user manual, schematic, etc.)? TIA

I was so much older then, I'm younger than that now...

Interesting

Apparently made by MITS the same people that brought us the Alitair 8080
computer.

MITS = Micro Instrumentation and Telemetry Systems a part time business
started by an Air Force officer.
He is the guy that a dropout from MIT that had a 4K BASIC he wrote on a
PDP-8 went to see, the rest is history.

Last I heard the owner of this company had retired to ? Alabama and was
practicing medicene at a rural clinic.

Have no clue where you might find schematics or docs.

Still have two Altair 8080's one still works. I use a P-4 for a terminal.

Sorry got the numbers wrong

Altair 8080

And the owner of MITS was Ed Roberts.

Hugh,

Thanks for the reply. Barring my occasional 'senior moment' I too
recalled that MITS were the same folks who created/sold the Altair. I
have not been able to find, via an internet search, any information
about equipment (other than the Altair) made by this company. I wonder
if there is another MITS...
Spiders had become squatters in this equipment. After some wrangling
with their nests I actually seem to have this piece working. Working
defined as powers up, display intermittently works and signal voltage
present at the outputs. I don't have an oscilliscope so I am not able
to view the various waveforms it is supposed to generate. Oh well, it
is kind of fun to work on - discreet components (74 series chips) that
are socketed and removable (gasp). I haven't seen this kind of stuff
since college.
Aside: BTW, I have an IMSAI 8080 using a pair of ThinkerToys (George
Morrow's company) 8" drives and a video monitor (can't recall the
make). Funny how much of this stuff is still around.
Thanks again!

There's a good chance that it was a construction project in Popular
Electronics (or maybe Radio-Electronics) in the late 1960's or early
1970's. Both magazines were indexed in The Readers Guide to Periodic
Literature (or something like that). I remember they had an electronic
desk calculator project before they had the computers.

Mark,

Possibly a kit... I was a long time subscriber to PE and don't
recall (barring 'senior moments') any kit form MITS equipment - but
hey, ya never know. I'll try to pursue that angle at the library.
Thanks for the reply!
