Description

Zenith 85-3222-01 CPU Memory Board Proprietary ISA Style Expansion Card

A CPU and memory expansion board designed for Zenith computer systems. This proprietary ISA-style card adds memory capacity to compatible Zenith platforms.

Specifications & What's Included

  • Model: 85-3222-01
  • Type: CPU/Memory Expansion Board
  • Form Factor: Proprietary ISA-style full-length card
  • Bus Interface: Non-standard proprietary ISA (does not fit standard 16-bit ISA slots)
  • Date Code: 022486
  • Manufactured in Malaysia
  • Card only—special Zenith daughter board required but not included

Applications

Zenith expansion cards were used in Zenith Z-series and compatible computer systems from the 1980s for memory upgrades. This board requires a matching Zenith daughter board to function. The proprietary ISA interface means it is not compatible with standard ISA expansion slots found in IBM PC-compatible systems. Used primarily in vintage Zenith computing environments.

Condition: Used
This Zenith 85-3222-01 CPU/Memory Board has been inspected and appears to be in good used condition. It was pulled from a working environment where it was previously in service. The board shows normal age-related patina consistent with its vintage, and all memory chips and components appear intact with no visible damage, corrosion, or missing parts. Note that this card uses a proprietary ISA-style edge connector and does not fit standard 16-bit ISA slots — it requires the special Zenith daughter board, which is not included.
