Peter - I too have a ZX81. People, you should really come round my house and play on my Specccie, those of you whose first computer was a PC don't know what you are missing!
We can program Hangman in Basic (first time took me about 2 days to type the **** program in!). And we can play Rambo and save the prisoners.
Adam, I used to do the colors too. you just specified a few lines of Basic and then specified:
40 GOTO 10
OK let me see if I remember!
5 REM Hangman
10 REM set up screen
20 INK 0:PAPER 7:CLS
30 LET x=240: GO SUB 1000: REM draw man
40 PLOT 238,128: DRAW 4,0: REM mouth
1000 REM set up word
110 INPUT w$: REM word to guess
120 Let b=LEN w$:LET v$=" "
...and so forth
