We're now running reliably at 10MHz, but I reckon I'll build this up as a rock-solid 8MHz EGA gaming PC, perhaps with the option to switch clock speeds further down the line. I've been on all sorts of adventures trying to get EPROMs to work so I thought I'd share my findings in case they're useful for anyone else.

The Atari 5200 is an underrated console, in my humble opinion. But this one does have an annoying fault relating to a bad batch of CPUs. So let's get the soldering iron out and attempt to repair it using an official Atari "Tech Tip" sanctioned fix from 1983! Support the channel!

Wherein I explore some MIDI options for DOS gaming on my 486, have a look into the SoundBlaster "hanging note" bug and a few solutions to fix it, and compare and demo a few different Roland devices (the MT-32, SC-55, SC-88) as well as mt32-pi, a modern MT-32 emulator.
