It might be possible, however it is often a mistake to assume that the predecessor is so that you can emulate it in software in real time. The 6502 is still a fast microprocessor, especially when munching 8-bit data, and the VIC chip is a pretty tricky little gadget by itself. >Any comments?

Actually, you don't need a disk controller, the *hardware* is perfectly cable of driving the standard Commodore Serial Bus out through the parallel port. Unfortunatly, nobody has written a serial bus driver, primarily because the Amiga peripherals are much advanced over anything avaiable for the C64. I've heard of a number of projects attempting to emulate machine x on machine y. Generally, they get to the point where you can run k% of the programs at reasonable speed, but as you try to increase k, the emulation becomes slower and slower. Perhaps I'll be surprised someday. -- George Robbins - now working for, uucp: {ihnp4|seismo|rutgers}!cbmvax!grr but no way officially representing arpa: cbmvax!grr@seismo.css.GOV Commodore, Engineering Department fone: 215-431-9255 (only by moonlite)
