Hi, Someone sent me this yesterday and I thought it might be of interest to the various 6502 enthusiasts on this list. It's a PDF of the transistor schematic of the 6502 CPU. It's high resolution and fairly detailed (includes annotations of the various bits of the CPU). I put it up on my website at: http://www.shiresoft.com/downloads/docs/6502.pdf Have fun! TTFN - Guy
