If you decide to make a "little" board with a 6502 on it, then you also must put all the special peripheral chips of the emulated machine on that board. As far as I know this is always the hard (and slow) part of an emulation. To emulate a sheer processor is not such a hard thing, but to watch for certain addresses that are peripheral registers and then react accordingly, that takes real effort. So in the end your "thinggie" would carry about 70 % of the hardware of the emulated device. That's normally not worth the money. >How about a 1571 "program" to allow you to use your amiga as a >Drive for your 64. (Ie ya plug ya 64 into the amiga, and use it's >hard drive) ^^^^^^^^^^ Now that sounds nice! Regarding all those VERY few and expensive hard disks for the C64, this could indeed turn out as a rather effective solution! You know there are already handler programs existant for the Amiga to access the serial bus, and the hardware interface is also well-known. The only thing one would have to adapt is that the software (as far as I know) wants to act as the bus controller, like the C64. So this would have to be changed to act as a passive bus device. Sounds really like a neat little project. Someone volunteering? -- Best regards, Dr. Peter Kittel // E-Mail to \\ Only my personal opinions...
