Pulled this out now that I have some things that were in front of it out of the way.

Here it the pitch on it.

The Good:
Cabinet is in pretty good shape with a few dings and scratches here and there.
I would say the art in in great shape. The pictures do a nice job of showing condition. I have not wiped it down so it would look even better cleaned up.
It is complete, from what I can tell, minus the door to the coin vault and the shifter knob. I did notice a carriage bolt missing from the dash.
Nice, clear gauges in the dash.
Nice art on the "Start" button, at the shifter hole, and in the wheel center.
Great bezel.
Double stripe t-moulding is in very good shape IMO. A couple of little nicks but overall very nice.
It even has a complete coin door with mechs, good reject buttons with the art in them, and good lamps there and working.
I have a spare set of boards (See Below)
I do have the back door (It's not pictured)

The Not So Good:
No image on the monitor.
When powered up the game makes a game sound of some type. Its apparent its not some random "noise" or speaker pop, but goes no farther in that you cannot coin it and play it blind. The displays roll a seemingly random assortment of numbers. I swapped in the 2 main boards from the spare set and it does the same thing. I have done zero trouble shooting on the game beyond that. It may be missing a voltage, have a low voltage, or something else that would make the 2 boards act the same way in the one cab. It could also be in the smaller 3rd board I did not swap. I can see that one of the connectors to the outer board is a little toasty. I want to say its the top most Molex labeled "A". A good cleaning may also do wonders to get it closer to working as there is a fine patina of dust in the bottom. The fuse block is definitely in need of a cleaning!!
The large sub in the kick panel will need to be replaced or re-foamed. The cone is there but the foam has long since flaked away.

The Mystery:
I noticed that the board in the game has a silver box mounted to it with pins inserted into sockets on the board. The spare board has the corresponding locations populated, and had mounting holes in the same places, but no silver box. Turbo fans may know what that is. Some factory mod, upgrade??

$100 as is, where is, with spare board set.

Nice price for a decent project - just sold my Turbo project. Free bump...

BTW - used the Priest ref in my post, too :D
 
Well, I'm out of Judas Priest references....
....but still have a Turbo.
Offers? Trades?

The sound you hear on power up seems to be the sound board's self check. This is good news, and points to the sound board being in working order!

Sega had the games main code scrambled (on the 3 EPROMs next to the processor)The mystery silver box contains a specialized processor that unscrambles the code. So, the silver box is original. Someone decrypted the code on the 3 EPROMs so it could be used with the generic version of the processor. If the stickers on the EPROMs have different numbers between the 2 boards, then someone did this fix to replace the processor.

The high score display also should be error free. Mine did the same thing. Once you get the voltages correct coming from the power supply, check for discontinuity between the processor and the board. 3 pins on my game's processor were discontinuous (turned out the solder pads were gone), so I ran a couple jumper wires and the game booted. This got rid of the junk on the high score display. Not too bad of a fix if you can solder and use a multimeter.

Hopefully this helps with the sale by giving prospective buyers hope. The cab looks to be in pretty good condition, it even has the elusive coin bucket. Good luck selling it.
