Getting those flashers to work was a PITA, thanks to Quench for pointing in the right direction!
The back mirrored panel has 1" clear starburst playfield inserts glued in place with socketed 8SMD Comet flashers. I used the clear inserts so colored flashers can be swapped in so the look can be tuned to taste depending on which game is in the machine.
Officially as far as I can think of this wraps up the Seawitch portion of this project. Its 100% ready for Pintastic and the next phase of the project will focus on a Bally title dropping into the cabinet while maintaining Stern compatibility of course. I'll decide if it will be covered here or not in detail or make a separate posting.
In a nutshell this will involve the following;
1) Transformer update to later Bally spec (with -54 rectifier board) with backward compatibility to early titles. The only real hurdle here is the playfield to A2 board connection is different so will either just make a short adapter harness or graft a second connector to the Seawitch playfield harness. An adapter makes the most sense as there will be other titles down the road that also use the early rectifier board connection but the grafted connector is electrically more appealing.
2) Logic flipper switches need to be added to the cabinet harness (lane shift)
3) Bally soundboard wiring needs to be integrated into the cabinet. Going to start with Squawk and Talk board wiring, may make a "plug and play" harness for easy swaps for early Bally titles. Have to consider the different volume controls Stern and Bally utilized so they don't clash.
At the moment here is a list of future "expansion modules" I have my eye on. Aside from Centaur and Quicksilver no particular order as you never know what will show up.
Bally Centaur
Stern Quicksilver
Star Trek
Eight Ball Deluxe
Skateball
Kings of Steel
Galaxy
Night Rider
BMX
The list is not definitive, some will depend on what pops up or not and what catches my eye if the gameplay looks interesting. A few Bally titles I already own so not looking to duplicate (Xenon for example)
Star Trek I'm looking to obtain so I can try my hand at custom rules and sound as I always though the title suffered from weakness in those areas.
Flash Gordon (II) I'm still on the fence about making a drop in or completing the whole cabinet.
