Yes, as far as I can see. The emulation of TOS on a CP/M-68k machine would mainly consist of remapping the traps (I'd probably have to redo some arguments - trap numbers etc) as the functionality is there. Also, all the things that you *can't* do on CP/M-68k would have to be caught.. . >Have you considered porting MINIX-ST to the CP/M machine? Yes, but I don't have the time. The only problem is that I can't (easily) get to the I/O system, since it's tied to a Z80 computer. The machine is basically a HUGE Z80 computer with a 68000 board tagged on top, communicating through shared memory (the machine is a SORD M68). It would be fun though, although my enthusiasm for the machine slumped somewhat when my experimental CP/M 80 system zeroed the disk block containing the directory on my working disk.....
