Ok, what's going on with this tape is manipulation of (integer) BASIC
pointers, using memory at the traditional beginning of BASIC space
($800) and that's about it. With an integer machine (or with an
Applesoft machine booted with the 3.3 System Master disk) you can run
the program by:
1) save off the zero page stuff from the .wav
2) save off the $800 stuff from the .wav
3) boot the DOS System Master (or boot your Integer machine)
4) get into Integer BASIC
5) bload the zero page stuff
6) bload the $800 stuff
7) RUN
