You can power your Mac 128k / 512k or Plus mainboard outside the case from a regular ATX power supply.

Outputs video to an external VGA monitor. Use the regular keyboard & mouse.

Great for trouble-shooting mainboards or video capture.

Uses a Raspberry Pi Pico to output a VGA signal from a Mac Plus / 512K / 128K

Can be captured on a PC using a VGA to HDMI adapter & HDMI to USB capture adapter. Also has audio breakout.

Will include a link to 2x UF2 files for the Pi Pico1 and Pico2. Pico not included, available elsewhere from £5.

This design uses 5v to 3.3v level shifters so you won't fry the Pico.

This is the self assembly kit shown in photo 1. You may need to cut the locking tab off your ATX PSU plug to fit.

As this is a kit, you can alternatively leave off the ATX and Molex connectors and just run 5 cables out from the Mac

to the board and have an external video capture setup - which should work with SE, SE/30 and Classic Macs too.

Shipping via Royal Mail UK (48 hours) & Worldwide (7-14 days).

I've also tested it with this small inexpensive Pico ATX power supply https://www.ebay.co.uk/itm/405108482467 that takes a 12v 2a barrel input.
