SO my ZX81 is at work still as the Mrs doesn't want me to bring it home...and since its functioning on 1K for the time being I have been using a few Sinclair Programs listings and of course JK Greye Software's "10 games for 1K ZX81".
Guillotine (rather like hangman) is proving quite a hit. My colleagues leave the ZX81 with a word to guess, and somebody comes along and plays the game, tries to guess the word. This has been going on all day today....we have four people playing it, leaving words for each other
Something so simple, yet proving popular.
