The Pitfighter programmers decided to disable watchdog for 
field test because they wanted to hear about it if there were 
any lockups. Unfortunately, the PCB does not reset properly, so 
the game takes several tries to come up. Last week, we assumed 
it was just one board. When two more boards exhibited the 
problem today, I thought we should check into it. Sam had Glenn 
put a much bigger cap on the reset circuit (1uF) and the 
problem went away.

I would guess what is happening is that the reset line is going 
high before the voltages are stable, and the processor tries to 
bring the system up but can't. Should we investigate this 
further and change the values around for the "standard" reset 
circuit so that reset does not go high until the voltages are 
really stable? I'll bet your nifty new scope could find the 
problem pretty quickly (if driven properly).

This may apply to more than the G1 hardware.
