ZX-81 architecture overview and repair, mod and upgrade plan

The Byte Attic 29 min Published Jun 2020

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.
