I have finished the 3rd phase of my IBM 1410 SMS computer
reverse-engineering project. The first phase was writing a software
machine-cycle simulator - almost 20 years ago, in part to verify I had
usable software. The 2nd phase was writing code and setting up a
database to do the 3rd phase - captur
I did that sort of thing for my PDP-8/L, where the reader run drove the
RS-232 "CTS" control signal and wrote a "C" program to do simple TTY

That code would not run in Windows of course, but it wouldn't be all
that difficult for someone with a C programming b

Typically the files on Thingiverse are .STL format, which is portable 3D
model. One feeds it into a slicer program (there are several to choose
from) to produce GCode that uses the specifications of one's particular
printer so that the right GCode gets spit out.

Fiche - I have no ready way to scan them. Hundreds (in several
different DEC groupings). Not likely anytime soon.

The iSBC 202 is actually two boards: a controller, PSA 1000467 and a
interface board PWA 1001036.
There are 4 PROMS on the controller/channel board, intel D3604 (512x8),
labelled A10: 52-722, A11: 52-729, A12: 52-741 and A13: 52-735 . I
presume these are what you are looking for.
Unfortunately,
Neat.

Yeah, info does seem to be scarce. Not even in my LEVAX fiche set.
But maybe decipherable? Since three of cards are the same (per the
Wiki), those interconnections would presumably be the same as the
RK11-D. That fourth card (M7268) is apparently a connector card for the
Q-Bus and drive bus. N

As some here probably know, I have been working the last couple of years
working towards an FGPA gate-authentic replica of the IBM 1410 - the
larger cousin to the IBM 1401.
In 2018 I developed an application for gathering information of of ALDs
and stuffing it into a MySQL database, then spent the
