Recently a friend of mine wanted me to turn his 6502 computer into a faster machine.(ok, ok, his commodore 64). After some research I found a 65C02 which is a CMOS 4mhz version of the 1mhz 6502. I also saw a 65C802, but no information on it's purpose. I would like to think it is a CMOS 8 mhz, it cost over twice as much as the 65C02, and this might be a good sign. I appreciate any comments on these chips. thank you.

Are there any firm rules of thumb for how much abuse a laptop with a running hard disk can take? I know they can be used in airplanes, for instance, but what about in a moving car or rougher vehicle (fire truck, for instance). Do any manufacturers publish information of this kind?

Shouldn't this be in comp.sys.cbm? Actually, I think there was a discussion of this in that group very recently. Anyway, note that the processor in the 64 is _not_ a 6502 - it's a 6510. While the two share a common instruction set, the 6510 has a small I/O port located at memory locations 0 and 1 which the 6502 does not have. Therefore, I wouldn't think that the 65C02 or 65C802 would work. Also, you should keep in mind that faster processors need faster memory (RAM _and_ ROM) and faster I/O chips. In summary, I would think it very unlikely that plugging either of those chips into your friend's 64 will create a working computer.
