Winsystems MCM-7508 - 48-Line Digital I/O Interface STD Bus Boards Simple Type: I/O Controller

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