From the project
A MiSTer FPGA inside of an iMac G3
The iMacSTer is an early 2000's Apple iMac G3 with a MiSTer FPGA multisystem emulator inside of it. It is intended to be a non-destructive modification so the iMac can be returned to it's original state if desired. The mainboard, drives and IO panel are removed and replace by custom hardware, but no cuts are made to the chassis and the new hardware connects to existing internal connections without the need for any soldering. That being said, I can make no guarantees about the long term implications of these modifications. The speakers are being driven by a different amplifier than they were…
