Re: WANTED: Case and Function key plastic

If it's of any use, I once successfully removed permanent marker from an Apple Powerbook 180c using toothpaste and a piece of paper towel. I think it works as a very mild abrasive that removes the ink from the surface of the plastic, in a way that doesn't affect the surface texture.

Re: Repairing a dead A310 power supply

It's probably recommended to replace them, but those particular capacitors are not required for the power supply to function. I've often removed them or left the blown remains in place and continued to use the machine in question.

Re: CUB 451 with lots of interference

I've had this fault on a Cub before, and I seem to recall it was caused by the really big capacitor on the board (this was a series 3 board, and the capacitor was blue). I fixed it by swapping the capacitor with one from a spares PCB that I'd kept.

I've repaired that kind of thing before, by snapping the complete leg off an old or dead chip, and soldering it to the 'half leg' of the chip to be repaired.

I still have an AMX Super Art ROM somewhere that I had to repair in this manner after dropping it while cycling at 20mph.

If you've got an Android device, the app TapDancer purports to be able to play UEF files. I've not tested it yet (all my real hardware is packed away). Might be easier than trying to set the Electron up next to a PC.

If you've got an Apple device, I don't think there's an iOS version.
