At the birth of popular computing in the late 70s, Sinclair brought out its touch-pad ZX-81 with a whole 1K of memory! I remember figuring out how to plug it into my portable black and white TV and then tuning the set so that I could get a picture, although it was a little shaky at times.
I would then spend hours devising hangman-like games using BASIC's FOR-NEXT loops and CHR$, GOSUB and RETURN commands. It would be more than a little frustrating to have to press keys over and over again because they were not as touch sensitive as you expected to them to be! Also, they were at times oversensitive and a row of B's would appear on the screen, which would then have to be erased.
Ah, early BASIC and the ZX-81, a match made in computer heaven!
