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

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 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.
