[Coco] Hi-Res Joystick Interface Weirdness

[Arthur Flexser]

My guess would be that it is indeed the difference in CPUs, especially if
it is the 6309 CoCo that Max-10 doesn't work with.
The two CPUs handle illegal opcodes differently, which might cause
incompatibility.  Try swapping the CPUs, if they are both socketed.
