In this episode I take a closer look at a Sinclair ZX Spectrum +3 that seemed to have a CPU fault — but things aren’t quite what they appear. After some detective work the real cause turns out to be a simple physical issue, and a few extra problems show up along the way. I also take the opportunity to service the 3" floppy drive, cleaning out the old belt and fitting a new one to get it running smoothly again.
