I [Paul Lutus] didn't really "place" it in the public domain, I just let nature take its course.
The inevitable result is that there are now only versions of the program online in which my name
and copyright notice have been removed: http://www.youtube.com/watch?v=6FDtXflMBmw
I searched for the original program online, but couldn't find it -- only the pirated version.
By "pirated" I mean someone has removed my copyright notice and offered the program as their own,
successfully replacing the original in all online archives.

Mr. Lutus I've changed only 2 bytes, will you forgive me?

Look at OBJ.HELLO, loaded at $800, there are three calls to the subroutine $0C4D and after
a lot of disassembly & tracing you can see that this is the copy protection check routine.
Put a $60 - RTS at $0C4D, then 800G

Yes! Here we go! The menu! Success! Ahem... no... not really... try to hit it does not no matter
what key... we stuck to the menu.

After more disassembly & tracing:

0A50 - 20 56 0A  JSR $0A56
0A53 - 6C 86 00  JMP ($0086)
0A56 - 6C 3A 00  JMP ($03A0) 

Bypass the routine at $0C4D and the wrong address is written in $03A0.

Put $2C - BIT at $0A50, then 800G and it's works!

Notes

- deleted "JERRY SR." this is only the music player, it can be saved by the M -> G
  options of the menu.

- I own a //c, can't test the tape output and emulator are useless in this case.
