Evening folks. I have been working on a design that requires a high speed 6502. I checked out the GS65C802, but was told it was too expensive and was no longer manufactured. Does anyone know if a 6502 greater than 4Mhz exists. Or if rockwell have other processors that are faster and compatible with the 6502's instruction set. I Know that my GS has a 65c816, but thats over kill for my task. My programmer is not farmiliar with 65c816 anyway. thanks in advance steve h

In I.C. Master 1989-1990 I saw an ad by Commodore Semiconductor for a 10MHz 6502 compatible micro. Don't know what happened to the chip, or to Commodore Semiconductor. Len.

Don't know what happened to the chip, or >to Commodore Semiconductor. Len. I've seen an ad for a 12Mhz chip some years ago. It was a 65c02. All the fast ones are CMOS. Also you might be interested in the chips made by WDC, the 65802 and 65816. The 65802 is pin-compatible with the 6502 and has a 16-bit internal architecture. It also supports a 6502 'emulation mode'. The 65816 is the same as this but has a different external interface. This lets it support up to 16Mb of address space. Both of these run up to 8MHz. Teik Fish (using Andrew Williams' account)
