GEORAM expansion clone for Commodore 64/128 V2.1
This is a PCB for a GeoRAM expansion clone for Commodore 64/128.
Version2.1 - 22.4.2023
Description
3rd RELEASE!
This is the release 2.1 with little improvements.
What you get is a PCB with NO SMD components, so it is easy to mount, and there is even more; the attached issue N.8 contains the description in detail of the circuitry. This project has no secrets for you.
Changes from the version 2.0:
- The mounting hole has been moved to best fit the into the C64 cartridge case.
- The tracks around the mounting hole have been redesigned.
refer to the BOM for the components list.
It is a card you can easily assemble by yourself, I avoided any SMD component.
Happy tinkering!
