From the project
ROMY is a small add-on PCB that enables Amiga 3000 / 4000 computers to use 1MB (or larger) Kickstart chips.
ROMY is a small add-on PCB that enables Amiga 3000 / 4000 computers to use 1MB (or larger) Kickstart chips.
This project aims at iterating and improving the existing Romy designs.
Look in the software directory for a bunch of scripts to create a nice 1MB ROM image for you.
There's also a small program to create parametrized PLCC plug footprints for KiCAD.
The logic directory contains the contents for the GAL 22V10. If you want to build a ROMY yourself, you will need to program this before soldering your GAL down.
