Today was a good day... in short; Star Trek: The Mirror Universe LIVES.

A design short-sight with the MOSFET LAMP board I designed rendered the LED switched inserts too dim. Basically; I had forgotten that the MPU scans each LAMP in sequence which in effect cause the LEDs to be on for only a short period of time. I can't fix the design (will require a board spin at a minimum) in time for TPF; so I had to go back to the original lamp board... along with shoehorn in a 6.3V Switch GI transformer from radioshack.

ShertzPinball loaned me a untested Lamp board which I debugged and was able to get the lamps functioning well enough for TPF.  Thanks Jason!
All but one lamp is working... the outlier is the 10K bonus section on the primary hull of the ISS Enterprise. I'm planning on further debug after I get it buttoned together. I suspect a bad SCR; but will have to test.

MPU was going straight into Diagnostics... or resetting after the machine entered Attract mode. given it was going into Diag / test mode was a clue... turns out that the 6821 PIA at U10 had pin 40 bent under the package instead of into the socket. This caused the flakiness.

All solenoids are firing under test; ball ejects into the shooter lane.
All switches adjusted so switch test passes. Original soundcard passes tone test.
Proximity sensors tested and verified working.

3 of 5 displays are installed in Pl1,2, and the credit window. All pass the diagnostic digit count.

Coin door reassembled and attached to cabinet. Lockdown bar hardware is being cleaned and prepped for re-install tomorrow.
Hope to install side rails and misc cabinet hardware tomorrow.

Sunday I hope to finish the last two displays and install them. It's at this point I'll probably drill the hole for the left handed shooter.

So; What Do I have to report? Let's finish up the picture bomb from last weekend's work. Rather than post a bunch of individual plastics images... I've created a panoramic stitch of several high resolution shots. Feel free to click the picture/link and look at the detailed original image: ( yeah... it's HUGE... so big it wouldn't load in IE11. Chrome or FireFox)


Each plastic (except the orbits) has it's own protector. There is protective transfer tape over the backglass... which will stay on until TPF to reduce scratches.
