A few days ago, someone on the net posted a small BASIC program which patches
various versions of ProDOS, including the yet-to-be-made-public ProDOS 1.4.
It wasn't made clear in the listing, but does the program fix the bug that
causes your second floppy disk to be activated during normal disk I/O with
other devices?

I editted the program so that every line that did a POKE would be listed out.
When used on ProDOS 1.3, quite a few addresses were modified.  The only bug I
was aware of in 1.3 was the 65C02 "BRA" instruction, which is repaired by a
single-byte patch.  What exactly do the other POKEs in that program
accomplish?
