Applications

This card type was used to add or expand I/O capabilities in IBM PC XT, AT, and compatible systems running 8-bit ISA architecture. It supported legacy parallel printers, serial devices, and joystick input through a single expansion slot. These cards were common in industrial and business computing environments where multiple I/O connections were required.

Condition: Used
This SD-101 8-Bit ISA Multifunction I/O Card has been inspected and is in good used condition. It was pulled from a working environment where it was in active use. The PCB shows typical light handling wear consistent with normal service life; no cracks, burns, or damaged traces are visible. The DB25 parallel and DB15 game port bracket connectors appear intact.
