Applications
Multi I/O cards like this were standard expansion components for 1980s-era IBM PC XT and AT systems, supporting printers, modems, and serial peripherals. Historically used in business computing environments where additional ports were required. Suitable for system restoration, retro computing projects, or legacy hardware documentation.
Condition: Used
This DTK PTI-209 Multi I/O ISA card has been inspected and is in good used condition. The PCB is clean with no visible damage, broken traces, or missing components. The DB25 parallel port and DB9 serial port bracket connectors are intact and show no bent or damaged pins. Typical light shelf wear is present consistent with storage from the late 1980s. Please view our photo set and contact us if you have any questions.
