Description

Vintage Motherboard PG4403-04 VLSI Chipset ISA Slots PS/2 Serial Parallel Ports

Used industrial/telecom motherboard with VLSI chipset and proprietary form factor. This board served as the core component in legacy computing systems requiring ISA expansion capability and multiple I/O connectivity options.

Specifications & What's Included

  • Model: PG4403-04 (VLSI Chipset)
  • Memory: 2 x 30-pin SIMM slots
  • Expansion: ISA slots
  • I/O Ports: Parallel (DB-25), Serial (DB-9), 2x PS/2, DB-15
  • Floppy Controller: SMC FDC37C651R
  • Power: AT-style 20-pin connector
  • Board only — no CPU, RAM, or accessories included

Applications

PG4403-04 boards were used in proprietary industrial and telecom systems requiring legacy ISA card compatibility and multi-port serial/parallel I/O. The VLSI chipset and AT-style power configuration indicate use in 1990s-era dedicated control or communication equipment. This type of non-standard form factor board typically remains in use only within its original system architecture.

Condition: Used
This PG4403-04 vintage motherboard has been inspected and is in good used condition. The PCB is clean with no visible cracked traces, burnt components, or physical damage. The ISA expansion slots, SIMM sockets, and I/O bracket connectors all appear intact. The CPU socket is empty and shows no bent or missing pins. Minor surface oxidation typical of a board this age is present but the overall condition is good. No CPU, RAM, or accessories are included — board only. Please view our photo set and contact us if you have any questions. 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.
