From the project
8MB FastRAM Board for the Amiga 500 & Amiga 500+
This project was created in KiCad 5.1.2 - all the files you need to build this project have been added here.
You'll need the custom library files at the very least.
I've included the SPECTRA DSN export from KiCad and the Freerouter Session file as a baseline.
