TL866 Programming Adapter for 29F400/29F800/29F160 Flash ROMs
This repository contains the KiCad project and Gerber files for a TL866 Programming Adapter for 29F400/29F800/29F160 Flash ROMs which are used to replace 29C400/29C800/29C160 EPROMs in retro machines like the Amiga.
The subdirectory "gerber-files" contains a Zip file you can use to order the PCB from PCB manufacturers like PCBWay or JLCPCB. Simply upload the Zip on their web page. I recommend to order the standard PCB thickness of 1.6mm and HASL finishing.
