Specific to, I'm guessing, the banking hardware of the Laser 3000/Dick
Smith Cat? (I saw a disk image on Asimov with your name on it that
mentioned the Cat. I've used a Laser 128, but never a 3000 which is
apparently a bit more different from a real ][.)
It might be made to work on a real ][ with some heavy wizardry. I think I
saw someone on comp.sys.apple2 talking about doing that a few months back.
Running some sort of *x on an Apple ][ would be interesting, seeing as
it's been done on the C64. I actually own an Apple //e.
-uso.
