Vintage 8-Bit ISA Parallel (LPT) Printer Interface Expansion CardClean 1993 Silicon — Onboard Jumper Matrix Legend — Model LJKMP101C

Up for sale is a clean, visually pristine vintage HMC 8-Bit ISA Parallel Port Expansion Card (FCC ID: LJKMP101C). Manufactured in late 1993 (Component Date Code: 9348), this legacy expansion board provides a single external 25-pin female parallel interface port to link legacy computer systems out to classic Centronics printers, early external storage enclosures, or vintage software security keys.

Featuring a universal 8-bit interface footprint, this card slides natively into early 8-bit IBM PC/XT slots or full-length 16-bit ISA lanes on classic 286, 386, 486, and early Pentium motherboards.

🕹️ Integrated Silk-Screen Jumper Matrix:

This card features a highly convenient configuration table printed directly onto the green circuit board masking layer, allowing you to configure hardware resources cleanly with standard jumper blocks:

• Selectable Base Addresses: Route hardware configurations to native LPT1 (3BCh), LPT2 (378h), or LPT3 (278h) addresses, or completely disable the card.

• Hardware Interrupt Mapping: Features direct header pins to map requests straight to IRQ7 or IRQ5 to prevent device conflicts inside pure DOS environments.
