Picked up a Williams Pennant Fever not too long ago and had a little
time to play around with it today.
When I purchased it, other then some GI turning on, machine did nothing. Replaced the power supply with another I had sitting around, have all my voltages, but no life on the MPU. Measured 5V, 12V & -12 on the
connector. And 5V at some of the chips. Board has zero battery damage.
Nothing on the 7 segment display, nothing at the displays (tested those voltages as well at the power supply had my +100 & -100).
Would the cpu itself cause absolutely nothing to appear working?
Any help appreciated.

Oh and not that this was a high production game, but I did see it has
proto eproms, which i kinda thought was neat.

Hi Paul,
Are there any LEDs lighting on the MPU board - the one with the batteries?
If not then I would suspect the power connector to the MPU or at the
power supply first.
Check for 5VDC on the MPU itself before assuming power is actually good.
