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

Those 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.

It was for Microsoft 8K BASIC for Altair.

You're right that Nova BASIC didn't/wouldn't use POKE: it wasn't a keyword in either Single User BASIC (1970) or the later Extended BASIC. But Basic Computer Games Microcomputer Edition on page 158 says it was written on a DG Nova 800 …

On the next page, though, the program listing states:

180 REM *** CONVERTED TO MICROSOFT 8 K BASIC 3/16/78 BY JOHN BORDERS

I can't find a list of handy pokes for Altair BASIC, but they must've been out there at some time.

    Ah, I did not clue to MS being Altair in particular, but in retrospect...
