We had these in school in 7th grade (82-83). I just did run/stop. Shift-clr/home. NEW 10 PRINT "HELLO" 20 GOTO 10 LIST Li RUN run/stop. POKE 59468,14 and that is about all I remember.
Not to forget the Sinclair ZX80 and ZX81, marketed in the US by Timex. Sinclair at least had the sense to assign each BASIC command to a single keystroke.
This is a recreation of one of the scenes from the Commodore 64 demo disk, for any Commodore PET.
