Apple

A new version of this project is available here

The big brother of our previously released expansion card. The RAMGS-MAX will expand the memory of the apple IIgs to the maximum allowed of 8MB.

The apple IIgs is the most advanced computer in the Apple II series. Equipped with a 65c816 8/16-bit CPU with 24-bit address space it could address up to 16MB of memory. The original rom 01 model shipped with 256KB of fast RAM, the revised rom 3 shipped with 1MB (both had an additional 128KB of standard RAM and 64KB of sound RAM). RAMGS is a newly designed 4MB expansion card for this great classic computer.
