Been spending the last few nights chasing the bugs out of the system. Got the MPU board to boot, but goes straight into diag mode instead of attract mode.
Had a Soleniod board with a bad 'LS154 decoder. The ChipSelect pin was shorted to ground; causing the coils to fire every time the soundboard was accessed. It was pretty funny to hear the star trek theme being beat out by coils on the PF.

Tonight I worked on some of the lamps and began reassembly of the coin door.

Since that's all I have to report; let's take a step back in time and continue updates from this past weekend.

The Plastics were installed given the ball guides were completed. One of the pet peve areas of the original Bally is the darkness of the Enterprise plastic behind the drop targets. Given the entire machine is planned to be LED for it's entire life; I don't have to worry about lamp heat melting the posts. So; drilled a hole between the two posts:


I promptly voided the warranty of one of Comet Pinball's LEDs by removing the Bayonet Base and collar... then soldered a Green and Orange GI wire to the diodes.


I saved the 30ohm current limit resistor from the base and soldered inline under the PF:

Connecting the wires to the base of a GI lamp socket nearby.
