Intel OverDrive ODP486SX-20 Processor

S-Spec: SZ675 | A2 Stepping | Copyright 1989

Genuine Intel OverDrive upgrade processor from the original 486

OverDrive lineup. Despite the "SX-20" naming, this chip is clock-

doubled internally and was intended as an upgrade path for 20MHz

486SX systems. This early OverDrive naming scheme (SX/DX designations

before the DX2/DX4 branding) makes it a notable piece of Intel's

upgrade-CPU history from the early 1990s.

Specifications:

- Model: ODP486SX-20

- S-Spec: SZ675

- Stepping: A2

- Package: Ceramic PGA with Intel OverDrive branding

Condition: Pulled from a larger vintage CPU collection. Please review

photos closely for pin condition and surface wear. Sold as untested/

as-is unless stated otherwise.

A great find for 486-era collectors and anyone tracing the history of

Intel's OverDrive upgrade processor line.
