6502 pods & clocks....

Tic, tock...

The 6502 will clock from either a crystal or an R/C system. The problem
with the R/C is the capacitor is only 10pf, so the cable capacitance
will sloooowwwww the clock down somewhat (900kz to 500kz or so).

So, being impatient I'm making a simple 74044 1Mhz R/C clock that fits
into the Fluke adapter socket and will drive the UUT 6502 CPU directly,
thus the pod won't interfere with the clock frequency and I won't get
any more timeout errors (I hope).
