The ZX80-ZX81 Upgrade
The ZX 80 was the first Homecomputer from Sinclair, maybe the first Homeocmputer at all. It was followed by the ZX-81 soon.
The ZX 80 was sold as complete machine and as Selfbuild-Kit. The complete Version was sold for 498,- German Mark.
With Release of the ZX-81 Sinclair broght an Hardware-Upgrade to make the ZX-80 to a ZX-81. This Upgrade contained a new ROM-Chip and a new Keyboard (see Picture).
Cause the small amount of produced ZX-80s, they are very rare now.
