8-Bit One-Bus Flash and SRAM cartridge prototype breakout boards

Breakout boards for Flash, SRAM, and an edge connector for wire-wrap prototyping of cartridges for one model of low-cost home computer used in Asia. These were the images I used to home etch breakout boards using the toner transfer method. Images were made in Inkscape because at the time I hadn't yet learned any EDA software that would run on my home computer.
