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.
Well I'd keep it.
Thats the original IBM PC motherboard. The only other question would be
which of the first few bios revisions it has.
