ALL RAM is socketed (in reply to an earlier post). The RAM is marked MOSTEK
MK4116N-44GP. There are two circular 5-pin sockets near the power connector
at the back.
Thanks, everyone, for the help. I'll keep it safe somewhere.

Hi guys/gals
I have an old IBM motherboard in front of me, and not really
sure if it's
worth keeping/trading or (gasp) trashing.
It's marked
"16KB-64KB CPU" on
the top, 3 of the 4 banks or RAM are occupied.
IBM chips are dated
1981/1982. Otherwise I don't really know what to look for in identifing
this.
That sounds like the original IBM PC motherboard. To confim this, there
should be 2 DIN sockets at the back near the power connector. And the
RAMs should be 4116s or equivalent.
If I'm right, then IMHO you should keep it. The later version (64K-256K
using 4164 RAMs) is a lot more common.
