This video was more or less put together for my reference when trying to get some Sega Mega-CD dev cards working on a P3 800MHz board. While it was compatible as far as I could tell, I did not have a PC case big enough.
So we worked our way down the food chain to a Pentium 100MHz… What’s that? Now it doesn’t work on an electrical level? Bah! Moving down the chain even further we have the humble 486DX4 100MHz. It works a charm. Throw in a Gravis UltraSound and you’ve got quite a workstation!
