We recently got a Digico Micro 16V computer including a Pertec 3342 disk
drive. It is a 16 bit minicomputer based on 74181 ALUs and a couple of 4k
core memory modules.
Since the condition of the system is not the best (dirt, dust, some
bent wirewrap pins), I'm looking for the usual information :

Hi
I worked with DIGICO’s in 1974.
Is it red?
Does it have a manual pull through paper tape reader?
Was it made in the UK?
I am most interested

I did a scan of the CHM catalog, and we don't appear to have it
We do have some other things, which I'll scan today

Al, so you're saying, "yes please scan the MPI 91/21 product manual"?

MPI 91/92 I meant.
Listening to Bob Metcalfe talk right now (15:30 CST), and there may be a
question and answer session. Any questions?

MPI 91/92 I meant.
I've scanned something called the "MPI Flexible Disk Drive Interfacing
Guide" for the Model 51/52

double sided 48tpi, with some micropolis-unique feature?
Nope. not the same. did a page by page comparison, *very* close on
most of the specs - but when you get to a J1 pinout diagram for the
cable, there are significant differences. The 51/52 uses extra lines
that the B51/52 shows as not used.

Be most grateful if anyone can advise here please. Rescued a TRS-80 MC10 from
deceased estate recently - it was headed for the bin
but got saved.
The original owner was a bit of an electronics hobbyist and his brother-in-law
tossed these boards in with the bundle I grabbed.

One last tidbit on the Micropolis floppy drives--the early drives (1014,
etc.) used a body/chassis made of steel plate. The later drives (1115)
used cast body parts.
It's also worth observing that the leadscrew positioner is probably the
best, as it's the dominant technology in 135 tpi 3.5" driv
