Hmm, about this...

I'm trying to figure out the list of time critical tasks :

-loop to SAVE to a cassette tape.
-loop to LOAD from a cassette tape.
-loop to move the disk II head's stepper.
-loop to write to the disk (every 32 cycles ?, iirc)
-loop to wait for data coming from the disk (*).
-loop to read the paddles.
-any sound-generating loops.
-??

(*)-very easy to fix, I guess.
