Many classic Macintosh machines end up suffering from failed power supply boards.There are many different reasons for this, but primarily, these computers are now well over 35 years old and power supplies, like all components, have a rated useful life.While we’ve seen adapter boards that convert from ATX to the power connector on classic Macs, this ATX+VGA module replacement goes a step beyond and adds a Raspberry Pi Pico to give you VGA out! It’s not clear from the description what the RCA connector on the right is for — we’re thinking possibly composite output, as audio is still handled by the motherboard.
There are also two JST headers on the board, which look like they are possibly designed to drive cooling fans.In either case, we imagine documentation will improve over time, as these are hot off the press and are ready for users to put them through their paces! It’s suggested that you could use one of the PicoATX DC supplies to make a very compact and modern replacement, and this seems like a great idea.This could also be an exceptionally useful tool for someone who often does repairs on these machines — you could easily unplug the built-in supply, connect this one with a VGA monitor pre-connected, and you can be testing with modern, reliable components in seconds.
