Arctic retro | Sinclair ZX81 Repair Challenge - Can These 4 Classic Micro-Computers From the 80s Be Restored? @Arcticretro | Uploaded April 2023 | Updated October 2024, 2 hours ago.
I got four poorly working to non-working Sinclair ZX81 machines. Can they be fixed?
Check out pcbway.com/setinvite.aspx?inviteid=481573 - great quality PCBs from just $5!

One has picture but no working keyboard.
One has very poor picture.
Two is completely dead.
In this video I try to fix them all in one go.
