(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.
