Available again: the 6502 microprocessor
The 6502 microprocessor now available from WDC (Western Design Center) and modernized. Now clock frequency up to 14 MHz (instead of 1 MHz as in the original). Would beat now the Amiga in speed.
He is expected to cost about 6 .

no, it's a 6502, not a 6510 :) so $01 wouldnt work.. also, i think, the 6502 would not work with a bus design, so you couldnt have VIC and a 6502 accessing the same memory.. but then i'm no electronics guy :) |

its true. appearently its not even pin compatible to 6502. useless regarding commodore stuff. maybe if you want to fix a NES then you may be lucky =P |

...but it is good to know that the new 6502 is a "he". :) |

here is a question to hardware gurus. is it possible to make an hardware add-on to 6502 to use it like a 6510? a small pcb with the new manufactured 6502 on top and regular 6510 pins at the bottom maybe? i'm not saying it would be useful, i just want to know if it is technically possible or do we need to do something extra inside the chip other than using its pins? |

Now that $00 and $01 adress is memory, yes ?
So when an instruction reads from adress 0 or 1 it reads from cpu ram ?
Not sure why i would want to have a 6510 compatible 14mhz cpu in the c64 but i actually thinking of ordering some of those cpus. Maybe one of those cool to do projects but newer used later on.
Do i want a c64 with loads of cpu time?
The vic20 has a 6502 :)

no, its an i/o port, not ram. and writes to 00/01 can not be "seen" outside the cpu (normally). |
