Jan Beta | Atari XL/XE Sally to 65C02 CPU Adapter @JanBeta | Uploaded January 2021 | Updated October 2024, 2 hours ago.
I'm testing a Sally to 65C02 CPU adapter board for the Atari 8-bit XL/XE series of home computers. // Kindly sponsored by PCBWay - Get your first PCBs free! - pcbway.com

The Sally CPU used in the Atari 8-bit computers is a variant of the MOS 6502 processor that adds a halt line to allow for better timesharing with the ANTIC graphics chip. The new CPU allowed Atari to use less extra logic chips in production and save money.

The adapter board I built and tested was designed by Bernardo aka The Byte Attic. The files to make your own and the documentation are available here: github.com/TheByteAttic/Sally-to-W65C02S-adapter
