SRAM Memory Replacement for C64 Assy 250407 and 250425


SKU: N/A Category:


This is my own design. Based on neatSRAM schematic by Pasi Lassila.

I wanted to create a drop in modern memory replacement for C64 long boards that use eight memory chips. Gaps between memory chips on 250407 and 250425 motherboards is different. My board can be used with both. Pin headers need to be soldered according to which motherboard the memory is installed.

This will also fix VSP bug
