OVERVIEW
The LPM/MCM-7508 is a general purpose TTL parallel input/output card with a total of 48 bidirectional lines. These I/O lines are organized as 2 groups of three 8-bit bidirectional I/O ports that interface directly to 2 independent industry standard 4, 8, 16, and 24-I/O module mounting racks (Opto-22, Gordos, etc.) The card is I/O mapped and processor independent.
