The same goes for the Amiga 500, 600 and 2000!
If you like using older hardware but are having trouble finding a replacement chip, or want a significant performance boost, then check out the PiStorm32-Lite and other PiStorm boards. These boards use the Emu68 bare metal 68000 emulator for Arm on the Pi 4, which is a significant improvement over the original PiStorm project. The current iteration does not currently handle networking, but Andrew Hutchings’ plans for this year may include bringing back that functionality.
In one example, he loaded up Quake and the game peaked at 90 fps, which is pretty impressive for 80s hardware! If you don’t want to modify your own motherboard, you can buy a PiStorm32-Lite for $90, and if you want a restored model, Amiga 500, 600, and 2000 motherboards are cheaper. If you’re not an Amiga fan, there’s also a motherboard for Atari ST and Sinclair QL fans working on their own versions.
