Unknown Card Cards





        Here is an item for the hardware sleuths. I got a mystery card,
cards at a flea market that has me guessing as to its function. It
appears to be a set of three cards, two piggybacked together and a third
related. The cards are by sequential systems and have a solid Q with
"print " thru the bottom of the solid Q.There are 2 Zilog chips
a ZO853006PSC ROM? and aZ80 CPU on the piggyback card . The "mother card"
has ram  a 4 pole dip switch and 5 interface connecters labeled A B C D P.
The mother board appears to contact only 3 pins on the connecter
to the AII socket. The piggyback card has a 25
pin D shell connecter on a 6 " ribbon cable.
 
        Card # 2 of the set is a half length card with a 26 pin connecter
on the end that looks like it could connect to the mother board with the
appropriate ribbon cable which is not included.This card also has a
4 pole dip switch and a Rom? that says Sequential Systems (c) 1987
rev P288B.
        Anyone have any thoughts?
