(Also, you should, like, look into making a power supply for the Amiga CD32. Because it totally needs one.)
Hm. I would find the CD32 being one of the easier consoles to power. It uses a "common" 4 pin DIN connector and is wired for +5VDC, +12VDC, GND, same pinout as the 1541-II and 1581 (though different amperages). The fourth pin is unused as far as I can tell. No need of negative voltages of any kind, no proprietary connector that nobody knows what it once was called, no crazy AC voltages. I would think that replacement PSUs for the CD32 already are on the market, if you can't have someone to DIY it for you.
