As you may not know, i’m really into old arcade games. Few times ago , one of my Sega Touring Car driver boards died. I tracked the problem to a secured PAL which didn’t work anymore. At that time, i sent a working PAL to Caius from http://www.jammarcade.net for dumping and he delivered !! (thanks again!!). In the end, i was able to resurrect the driver board.
After that, i told to myself, that it would be cool if i was able to dump myself those PAL. so i decided to build Charles MacDonald adaptor And i took it as an learning project to design the pcb using Eagle.
Et Voilà 😉 Find everything on my GitHub
