   Last night I carefully opened the #Commodore wedge PSU with flat screwdrivers, but the interior is filled with a potting resin which is stuck to the box.

   I measured +5V after the regulator, but it drops as soon as I connect the #Plus4 board.

   If the board was shorted, the fuse would have blown. So I guess the regulator is unable to source more than a few milliamps.

   I couldn't make further progress without tools. I'm literally working from my mother's kitchen! 🤓
