On the IIfx and the IIfx Reloaded, the two Peripheral Interface Chips use a 65C02 core running at 4MHz - they require SRAM to operate.
Here's a quick list of pin compatible 32K x 8 SRAM chips.

On a reloaded board you can just go for ISSI IS61C256AL in SOJ-28 which is still in production.
I made the pads for the SRAM large enough to take both, SOJ and the original wide SO footprint. Liked by Jockelill,trag,Volvo242GTand 2 others |
