REMOTE CONNECTION VIA A RIBBON
CABLE
Existing systems which contain 28-pin bytewide sock-
ets can be retrofitted using a 28-pin DIP plug. The DIP
plug, AMP Part Number 746616-2, can be inserted into
the 28-pin site after the memory is removed. Connection
to the cartridge is accomplished via a 28-pin cable con-
nected to a 30-contact card edge connector, AMP Part
Number 499188-4. The 28-pin ribbon cable must be
right-justified, such that positions A1 and B1 are left dis-
connected. For applications where the cartridge is in-
stalled or removed with power applied, both ground con-
tacts (A1 and B1) on the card edge connector should be
grounded to further enhance data integrity. Access time
push-out may occur as the distance between the car-
tridge and the driving circuitry is increased.
