This is a project to reverse engineer a Commodore VIC-20 memory expansion from the old 8-bit computer days. This repository has several versions of the board, a talk describing the process and related documentation.
The talk directory contains all the relevant presentation files and the pcb directory has various PCB design projects (currently mostly in Eagle 7).
There are some pictures of both the original boards and my rebuilds.
