Description
DTK PII-124 Color Printer ISA Card 1986 Vintage PC IBM XT AT Parallel DB25
The DTK PII-124 is a full-length ISA expansion card combining color output and parallel printer port functionality for IBM PC XT, AT, and compatible systems. Made in 1986 and marked clearly with the DTK logo and model designation on the PCB, this card is a genuine period piece from the early IBM-compatible expansion ecosystem. It mounts via a full-length bracket carrying two DB25 connectors and one DB9 connector, providing parallel and color interface outputs directly from the ISA bus.

Applications
DTK (Datatech Enterprises Co.) was a Taiwanese manufacturer that produced IBM PC compatible hardware during the 1980s and early 1990s, a period when the XT and AT platforms dominated the personal computing market. Combination I/O expansion cards like the PII-124 were standard additions to early IBM-compatible systems, which often shipped with few or no integrated ports and relied entirely on ISA expansion cards to add printer interfaces, color output, serial connections, and other peripherals. The DB25 parallel ports on this card would have served dot-matrix and early laser printers, while the additional connector provided supplementary I/O. Today, cards like this are sought by vintage PC collectors, hobbyists restoring period-correct XT and AT builds, and researchers studying early IBM-compatible hardware ecosystems. This card dates squarely from the mid-1980s peak of ISA expansion card production, before integrated I/O became standard on AT-class motherboards.
This DTK PII-124 ISA Color/Printer Card has been inspected and is in good condition. The PCB appears clean with no visible damage, broken traces, or missing components. The bracket connectors — two DB25 ports and one DB9 — look intact and free of damage. Normal light aging consistent with a card manufactured in 1986 is present, but there is no corrosion on the edge connector or obvious component damage.
