ZX-81 architecture overview and repair, mod and upgrade plan
About this video
The Sinclair ZX-81 gets an architecture overview and a tour of its board, then a repair, and the maker talks through plans for extensive modifications and upgrades.
Good to know: Repair work on the board is likely to mean soldering: burns and fumes, and old solder contains lead.
Why watch it
The upgrade plans are discussed, not carried out, so this is a board tour and a repair instead of a finished build. The maker lists an Ansmann APS 1500 switch-mode supply.
