DoG's Hx Mongrel build attemt

Post by DoG » Sat Oct 12, 2019 12:12 pm

Got myself a donor Atari STfm. A C070859 Rev 2.1. Tested it and it worked fine, so I know that the components are not faulty. Lucky for me it was super clean inside...

I haven't ordered any components yet. But I do have a 4Mb 72pin RAM module, some sockets and a 25 pin female and male connector already.
