Repair/Restoration: Sinclair ZX80

Back in July 2022, I posted a video of a fairly large box I'd received:    • Unboxing a fairly large box!  
In there were a number of amazing computers and today I'm focusing my attention on the ZX80 from that video. Released back in 1980, this was the predecessor to the ZX81 which was the first real computer I'd owned.

This is a pretty beat up example and I have no idea if it works, so lets breathe some life back into this little legend.
