   There are 7 smaller chips with 14 pins, one slightly larger chip with 20

It might help if you state what numbers are on the chips.



   New Info; perhaps this is a CP/M card?  I peeled up the sticker on the 
   large chip, and there is this little 1/4 inch glass circle.  I can see 
   into the chip.  And on the chip, I can just barely make out some numbers. 
   My best guess for these numbers are: D271*-7  (the asterisk could be a G 
   or C).  Then, 112D3DC5.  These are the only numbers I can see on the main 
   chip.  If this is a CP/M card, what would I do with it?

does the card have a large chip that says "Z80" on it? if so, its probably 
a cpm card. the chip you mention is an eprom, and the asterisk is probably
a '6', meaning its a 2K eprom. If this is the largest chip on the board,
then I doubt it is a cpm card.
