Help with mystery card ID?

[lacoss@cello.gina.calstate.edu (LA County Outdoor Science School)]

I need some help identifying a card.  It came out of a IIe.  The only
identifying marks I can find are what looks like a logo with the
letters NPH enclosed in a round-cornered box.  This logo is on the
card along with "Made in Taiwan".  The logo is also on a silver
sticker, along with the number 7.  This sticker is on the largest
chip on the board which is labelled MCM2708C.  There are 4 other
socketed chips on the board, SN74LS377N, SN74LS00N, and two 74LS74A.
The only other things on the board are various capacitors and
resistors, and a 16 pin header.  The cable attached to the 16 pin
header ends in a Centronics 36 pin plug.  This makes me think it
might be a parallel printer card, but I'm not sure.  Does anybody
have experience with a card such as this?
 
Thanks in advance,     Greg
