Support Noel's Retro Lab on Patreon: We take a look at the last of the ZX Spectrum models: The +3 with integrated floppy disk drive. We run into several issues, and we can't exactly repair them all, but in the end we leave it in a working state.
First the power supply wasn't working. We took it apart and looked for problems, but we had to simply replace it with a working power supply.
Then the Spectrum wouldn't start up correctly and would give a garbled initial screen. That we did track down to overloading the 5V line and a bad capacitor.
Finally, we did some servicing of the 3" floppy disk drive, but it still didn't work. We tracked it down to a likely misaligned step motor, but had to end up replacing the drive with a working one.
