README 

plays music in the background via the pt3player

loads high to $6000 to try to stay out of the way of BASIC

disk activity might mess with the interrupts.  Might be OK on
an Apple IIe but the sound will glitch

Tries to avoid zero page addresses but still uses 8 of them.
	Hopefully only stomping on Integer BASIC and Sweet-16
