Is there a schematic {printset} around for MSC-8?
I have never seen one (and I have plenty of printsets from back in the day).
I'd love to see one to verify differences between the 4Kbit and
16Kbit-stuffed boards. I'd consider taking one of my 16K boards and
turning it into 128K (easier desoldering than by unpopulating a 32K
board)
As to boards other than memory and CPU a front pannel
board either
the 8E style or 8A is very handy too.
The frontpanels for PDP-8/e/f/m are pretty obvious when seen on a pile
(and aren't seen on piles that often), but I agree that the
programmer's panel for the -8/a is something to look out for - I have
one ($50 a couple of years back), and would recommend them for anyone
who wants to do more than just hit a boot switch and fire up OS/8.
For the uninitiated, it plugs into the "standard" I/O board, the
DKC8AA, via two 40-pin cables. Pretty much any OS/8-running or
WPS-running -8/a I've ever seen, has a DKC8AA. It wasn't _required_,
but it was ordinary.
