What about using a bit of buffering circuitry (and possibly level reducing) and
using that cassette data input line? That's certainly unused under os9.

Also - you could get 'dirty' and write a program that interrogates the other
joystick input (using your OWN low level routines to manipulate the joystick
selector MUX and comparator - using the system's would obviously create the
problem you've encountered). Other possibilities include using unused lines on
one of the PIA's and hanging a wire out the back.

P.S. You could get some joystick tweaking code from the color basic rom
disassemblies, if you have the "UNRAVELLED" series. You'll need to be careful
to lock interrupts while you're manipulating any control registers and restore
things as you found them.
