Description

IBM 73G3224 8-Bit ISA SDLC Multiprotocol Adapter Card Long Slot Vintage PC

This is an 8-bit ISA adapter card designed for IBM PC/AT and compatible systems. It provides SDLC (Synchronous Data Link Control) multiprotocol communication capabilities via a DB25 connector, using Intel P8251A chipset control.

Specifications & What's Included

  • Model: IBM 73G3224 / FRU 73G3224
  • Bus Type: 8-bit ISA long slot
  • Interface: DB25 (25-pin D-sub)
  • Protocol: SDLC Multiprotocol
  • Chipset: Intel P8251A
  • Compatible: IBM PC/AT and ISA-bus systems
  • Card only; no cables or software included

Applications

SDLC adapter cards were used in IBM and compatible systems for synchronous data communications, particularly in banking, telecommunications, and enterprise networking environments. These cards connected mainframes and minicomputers to remote terminals and networks. The 8-bit ISA form factor places this in systems from the 1980s through early 1990s era.

Condition: Used
IBM 73G3224 8-bit ISA SDLC Multiprotocol Adapter Card in used condition, pulled from a working environment. The PCB is clean with no damage, broken traces, or burnt components. The bracket shows light scuffing and marks from normal use, and the DB25 connector pins are intact. No cables or software included. Please note: We have multiple units in stock — yours may not be the one shown in the photos, however, it will be similar in condition and function.
