Adapts a modern ATX power supply to a Power Macintosh 8600 or 9600 without cutting the computer's chassis.

For this system (exact model): The dedicated bracket fits the 8600 chassis without cutting it. Select an ATX supply whose inlet position fits the bracket. Mains-powered equipment can retain dangerous energy; only a qualified installer should perform the conversion.

The current store listed the conversion kit without an out-of-stock marker on 2026-07-24. The ATX supply and tools are not included.

Open hardware SCSI emulator with SD-backed storage, optional Wi-Fi networking, and host-side management tools.

For this system (exact model): The official compatibility list names the Power Macintosh 8600.

Current seller checks on 2026-07-27 found a $39 internal 50-pin Pico 2 W kit, a $49 assembled external DB-25 model, a $49 PowerBook model, and a $59 assembled Ultra Narrow 50-pin model at authorized seller ToTs RETRO. JCM also carried assembled Ultra hardware and model-specific Macintosh adapters. Prices, stock, included media, and support differ by seller. Ultra models require Berg or Molex power and cannot run from SCSI termination power. The initial Ultra hardware release is not yet open hardware, although its firmware remains GPL; the project says hardware licensing will open later.

pcigraphics cardvideo outputfirmwaresoldering

Converts selected PC Radeon 7000 PCI graphics cards for classic Mac use with a Mac ROM v226 image.

For this system (exact model): The Power Macintosh 8600 is explicitly supported. A converted Radeon 7000 draws substantial PCI power, so an aging supply can cause instability.

The pre-flashed ROM chip and a limited set of converted used 64 MB cards were listed without an out-of-stock marker on 2026-07-24. The ROM-chip product does not include a graphics card.
