[ DOCS ] : Turbo ROM MkIII Reference

f1: LIST: + CHR$(13)
f2: OLD + CHR$(13)
f3: RUN: + CHR$(13)
f4: Toggles something? ON/OFF (maybe fastload?)
f5: LOAD + CHR$(13)
f6: SAVE”
f7: @$* + CHR$(13)
f8: LOAD + CHR$(13)

I also found a couple more:

CTRL + f1: @N* + CHR$(13)
CTRL + f7: Disable Function Keys

Now before you go pressing CTRL + F1 be warned, THIS WILL FORMAT THE DISK IN DRIVE 8, and give it a label of “GAMES” and an ID of “DISK”.
Found that out the hard way, luckily it wasn’t a non-replaceable disk.

There’s also text in the rom that says: “RABECAPS SSERP DNA KSID-TSED TRESNI” which is backward for “INSERT DEST-DISK AND PRESS SPACEBAR”, which leads me to believe there must be a file copier in there someplace as well.

Use @8 or @9 to select device 8 or 9, @10 & @11 just give syntax errors.
