I was looking through the Super Star Trek code when I noticed this for the first time:
7540 REM INPUT"DO YOU WANT A HARDCOPY? IS THE TTY ON (Y/N)";A$ 7542 REM IFA$="Y"THENPOKE1229,2:POKE1237,3:NULL1
POKEs... anyone have an idea what system they may have been for? I believe this version was written on a Nova, but I wouldn't have imagined it used pokes for I/O.
