Hi - I finished the scan of the MPI 91/92. I did it at Kinkos and it cost
me $54, and wow that's expensive. I should have asked before I dropped off
the manual. I kind of assumed it'd be more like $20. I don't have an easy
way to scan a plastic spiral-bound two sided document with pull out
schematics unless I do each page by hand.
If anyone wants the file, it's real nice and suitable for
archive.org, and
includes schematics
https://www.vintagecomputer.net/MPI/
So that brings me to the question - Should I buy a nice scanner that
handles two sided and schematic prints?...I have so many things more I
could scan if I had something cost effective. That's the last time I do
the Kinkos thing. I prefer to do this kind of work on my own.
Also of note I just finished the RCA COSMAC Microkit manual MPM 103,
obtained from the Hagley Museum archives in Wilminton, Delaware. They have
a treasure trove there. It's impossible to assemble the Microkit without
the manual, each card has a specific slot in the backplane. This is a
computer made with an early version of the two-chip 1801 CPU card, before
it was called "1801". More info is on my web site. So far I have the
current loop operating but the terminal card appears to be on the fritz or
altered for some other purpose that originally designed. I cannot yet
interact with a teletype. The COSMAC Microkit is a complete microcomputer
that pre-dates by a month or two the MITS Altair. A worthy project.
Next - a nice ROHM 1601 sales brochure.
I try to scan only what appears to not already be available on the
better-known archiving sites.

just an update, I have not forgotten this task, I just
need to find time
to get to a two-sided printer. I really need to get one for my self with
big copy bay to handle schematics. That would really accelerate my archive
work

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" drives.
