The American version of the British ZX80 can be identified by the different placement of the TV socket and the use of a few different components to support the 60Hz TV frequency.
The ZX81 upgrade kit, simply called the ‘8K ROM upgrade’ has the keywords ‘DELETE’ and ‘ENTER’ instead of ‘RUB OUT’ and ‘NEW LINE’ on the keyboard overlay.
