Quoted from ExitWound:
I think I have the only Space Shuttle in like 300 miles. This town is so isolated it sucks.
The original speech board says "garbled" on the back, so I had little hope it works. Why? I don't know. Could just be ROMs. The power board was probably fine. However, there's a significant change in -12V at U48 when the game is on - it drops to -20V. To eliminate the possibility of it being power, I bought a Rottendog board and installed it, but no change. I feel better doing that anyway on such an old game, one that is in meh condition. The main CPU board I had was furnished by Ed Cheung and it works great as far as booting, playing, and operation - other than sound. I don't know if he actually checked it or not.
So I'm willing to re-sell the working boards to others if needed. I figure that I'd want that same courtesy if needing a hard to find board. I only paid $500 for the machine, so putting in a few hundred isn't terrible in my opinion to get it working.
Want to drive yours to PA?
On the bright side of things, the backbox looks good.

Don't forget to add fuses to the 2 rectifier lines. I literally just finished doing that.

Quoted from winteriscoming:
Is there even an aftermarket MPU available for these?

No, and I've contacted rottendog to see if they would and they said there isn't enough demand (only 3 machines used this CPU, so 15k boards at best). You can either ship it to Ed Cheung, bring it to a show like Chicago Expo and let Rob T repair it, or sell it off and let someone else repair it and just buy a refurb from K's arcade.

** edit: this must be recent, but pinballpcb is going to be releasing a brand new system 9-11c MPU board with updated non-obsolete components, this is awesome news!

The board was originally serviced by Ed. Did a great job getting the board up and running and playing. But I'm not sure if sound was tested. He says it was. But it doesn't work despite changing out nearly every part that is involved in the sound section.

PinballPCB's page says "updated August 2013". I don't have hope it'll be soon, but it would be fantastic if he did produce it.

I plan on doing the fuses as soon as the game's up and running.

If the process of going to a System 11 is easy enough, then great. i'm fine with that. But even System11 boards are really expensive to begin with. I feel I'm so close I shouldn't give up on the System 9 yet.

IT WORKS! IT WORKS!

Went inspecting why I had -12V at the header pin, but not along the circuit beyond it. Turns out that the header pin connector (the little wire clamp that goes in the hole) was green and broken in two. The pin wasn't actually in full contact with the wire leading to a huge loss of voltage.

I transplanted an unused pin to 1J17pin8 and IT SPEAKS! All sounds work. All speech works. I'm ecstatic! Now to put it all back together and see how it plays!

I have a flaky airlock clock outlane switch, a flaky A switch, and a non-functional multiball launch switch. I think they just need to be cleaned and adjusted because they all test out in diagnostics. Weak pop bumpers that need to be rebuilt.

It's a non-forgiving game. That left outlane is treacherous.

Any idea what switch I could order for the U-S-A lanes and the right airlock outlane? Seems as if the leaf switches are all mostly the same, but some obviously differ from another.

If you have some rollover switches that aren't that sensitive, you can try cleaning with a card stock piece of paper between the contacts, pushing the contacts together and moving the paper back and forth. Also try bending them a bit to so they're closer together initially. Sorry, I don't know the correct part number for replacements. You might find it listed in the manual.

I found them listed in the Blue Parts Catalog with associated Williams part numbers, but none of them are in stock anywhere. Not rollovers for the USA lanes, nor the outlane, nor the pop bumper switches!

I've tried cleaning them. They're intermittent during play, but respond perfectly on the DMM. Did Williams use gold contacts on their leafs? It doesn't appear so, but it might be some other plating material that would be removed if I used something more coarse than paper.

Look closely at the contacts, sometimes Williams would assemble them upside down.

Well, had a pop bumper failure which I believe stuck a coil on and blew the 3A fuse. I figured there would be failures. I didn't figure the more common parts would be out of stock though. Blah. I did have a 800,000 point game! Hehe.
