Here's a copy of the 6502 timing specs from an 1985 Rockwell Data Book.

(So far the best way to send scans, space wise, seems to be ZIP'd .BMP files,
maybe some newer .TIF formats would beat this, but all I have is Paint Shop Pro
5 and using that software, ZIP'd .BMP are smaller than all it's formats.)

I'll send the 65C02 in another e-mail...
