This is the Frankintosh project – housing a G4 Mac Mini in the case of an Apple //c. From all outward appearances, a stock Apple IIc or //c with a little wear and tear. Inside, it sports a 1.4GHz G4 with a gigabyte of RAM. A far cry from its original 1MHz 65C02 and 128K of RAM.
Everything you see is still fully functional. The original keyboard is rewired and run through an Arduino (Teensy) so it can be used as a USB keyboard for the Mini. MH has also maintained many of the original ports, and repurposed a couple for updated peripherals. For instance, the mouse/joystick port has been wired up to a USB port on the Mini. To plug into this, an M0100 mouse has been fitted with the guts of an optical USB mouse, wired to the original 9-pin connector.
To attach to the original Apple monochrome display, MH built a VGA adapter that outputs monochrome NTSC via RCA. Instructions and pinouts for the adapter were found here. To adjust the sync and refresh rate, MH used SwitchResX.
