Description
Commodore C128 (310381 R7) SRAM Adapter
This board implements a static RAM replacement for the DRAMs on a C128 with a 310381R7 motherboard.
You will have to remove and socket your DRAM ICs to install this board.
- The board uses cheap and common components
- You can choose to use SMD or DIP components
- Once the DRAMs are socketed, the board is easy to plug in and remove

Greetings.
Yes, I will add the BOM, but first I need to finish validating the PCB by using the 'HCT logic family. I'm currently out of some 'HCT ICs, so they were replaced with 'LS for the initial testing.
Once the BOM is finalized and validated, I will upload one here for assembly, in the meantime, the current BOM will live in the github page.
Thanks. We got it.
Just uploaded the BOM
Thanks.
Thanks.
