Description

DCA IRMA III 004930 Rev A 8-Bit ISA Coax LAN Network Card RJ-45 BNC

This is a legacy network interface card designed for connecting computers to Ethernet coax LAN networks. The card provides both RJ-45 and BNC connectors for network connectivity.

Specifications & What's Included

  • Brand: DCA
  • Model: IRMA III, MPN 004930 Rev A
  • Bus Type: 8-bit ISA
  • Form Factor: Full-length ISA card
  • Connectors: RJ-45 and BNC (Coax)
  • Network Type: Ethernet / Coax LAN
  • Card only; no software, drivers, or documentation included

Applications

This ISA network card was used in IBM PC/XT, AT, and other ISA-compatible systems from the 1980s and 1990s. It connects legacy computers to coaxial Ethernet networks. The card supports both 10Base2 (thin coax) and 10BaseT (twisted pair via RJ-45) connection standards, making it compatible with older network infrastructure. It is suitable for retro computing, museum exhibits, or systems requiring period-correct hardware.

Condition: Used
This DCA IRMA III 004930 Rev A 8-bit ISA coax LAN network card is in used condition. It was pulled from a working environment and shows normal age-related wear consistent with a card of its era — the PCB and components appear clean and intact, with no obvious physical damage visible. The bracket, RJ-45 port, and BNC connector all look to be in good shape. This card has not been powered up or tested at our facility. Please view our photo set and contact us if you have any questions.
