Just wondering if anyone knows what these chips are for/from/etc.

Interesting look to them. I would say EPROM but the magnifying window is weird...

Okay so I'm trying again, as the Classiccmp software is not letting my
post through with the correct name of the subject computer included in the
post (I've tried thrice).
My D#CM at TE II has begun behaving very strangely.
The computers began to develop keyboard issues a few weeks ago, which
resolved to be some or all of a set of small filtering caps (which on my
board, looked just like picofuses) that sit on the lines for the
keyboard/video port failing. Replaced those with 470pf caps (after I
incorrectly identified and installed picofuses the 1st time), the computer
now recognizes the keyboard, but now fails 9 out of 10 times to go through
a proper boot sequence, generating a randomly garbled version of the test
screen patterns and then sometimes attempting to boot the floppy (but
fails).
Anyway, if anyone has a mainboard left over from a Spare Time Gizmos
project and would like to get sell it, I'd be interested.
Thanks,
Tom
Folks
I have today collect a recent E-Bay purchase. It appears to be an IO
Selectric that has been left in a garage for a long period of time and is
very gummed up. It will turn over with the manual handle, and it appears to
try and type, but the carriage does not advance. All the tapes and chords
appear to be in place. I have put some pictures here:-

sorry for the long link. Does anyone have any suggestions as to which
manuals are appropriate, and which documentation was followed to allow it to
be used as a printer?

That looks like an Ohio Scientific C3-B with two 74MB hard drives.
I'd really like to get that, and I'm within reasonable distance, but I
don't think I'll be able to do it.
c 3b or c 3p?
I remember a model c3p.....
