One of the Spectrum had faulty RAM and -5, +12V was missing.

Probably at come point the RAM included and cracked the switch power supply for -5V +12V.

Instead of replace the RAM and fix the power I changed the RAM to more modern RAM and bypassed the switching supplied.

To do this I have to change the external power supplies to 12V since the GUI chips need that.
