The frequency of the crystal oscillator is not specified on the schematic. Whats the clock speed?
I left out that detail because I figured that I would be experimenting a lot! Right now (04/2005) I am using an 8 MHz oscillator; since the clock-extend state machine (which doubles the clock period for memory and I/O cycles) divides that by two, the actual processor clock speed for most cycles is 4 MHz. For memory and I/O cycles it is 2 MHz.
