space shuttle - getting in deeper

So I'm reading postings on forums about sound.  It could be the CPU chip, it could be the main sound processor chip, it could be a faulty op-amp.  I figure the easiest quickest fix is to just replace the two main roms for $10 each.  Worst case if mine aren't bad, they are good to have backups for the future (never know when roms aren't going to be available).  There's a guy out of indiana that sells them, so it shouldn't take long to get here:

If it's the sound amplifier, I guess I'm going to have to just start desoldering capacitors until something works.  I'm not so sure someone sells NOS of space shuttle amplifiers.  There is some troubleshooting in the manual about sound not working

So I might just have to go through it one by one.

One thing I do like about this pin is the fact that it has so much diagnostics built in.  3 self test buttons behind the coin door, and test buttons on the main CPU.  I don't know how modern pins are, but this is the first time I've seen this.

Anyway, here's a quick test of it playing with backglass installed

Space shuttle pinball setup

So I got my pinball all hooked up.  Sound doesn't work, but I did a of cleaning up.




















Already replaced the incadescent bulbs with LED's:

Sound still isn't working, all the rom chips there:

Also there's some corrosion on this board towards the top:

I've noticed that sometimes the LED versions of the #44 bulbs don't want to fit in correctly, but if I lightly squeeze them with a wrench, it fits better

won an ebay auction for another pin

Take a guess what it is!





Will post more about it (and pics and video) once it's in my basement all hooked up.

backglass cleanup

Well I took the best photo I could, and I'm still not satisfied with the results.  There's shadowing from my dark basement, and if I use lighting I either get hotspots or reflections.  also because the camera is so far away, the image isn't as sharp as it could be.

I think I want to do two things:
1. Take the photos outside on a cloudy day (to prevent reflection), but still have enough light to give natural color
2. Take 4 separate photos to increase detail, and also prevent the perspective skewing you get with an image.

This blog sort of talks about it, but it doesn't really go into detail HOW he took the photos.  I would imagine you'd want to at the very least use a tripod, but you'd also want to make sure the camera were perfectly perpendicular to the backglass everytime, otherwise when you merge them together your going to have uneven sizes (and it will never line up right).

illinois pinball club

So it seems the only pinball club in this area is this one:
http://www.pinballmafia.net

And it seems to be an exclusive club that is limiting members that I'm never going to get in, what to do?  Well start my own of course!  I posted an ad on craigslist, and got 3 responses right away.  So since I had some interest, I decided to just go ahead and toss up a website real quick (so it would start getting indexed by google).  It only cost me $1 to register the domain (sale at godaddy), and I found a pretty good reliable free host to point it to.  Anyway, if your in illinois, go ahead and check out the site:

Gator buyer?

Ok, so I registered my gator pinball on a database that tracks who owns what pinball when I first got it.  Just logged in tonight, and it turns out I have someone interested in buying it.

I find that so interesting that someone would look for a pinball they used to play when they were younger.  It makes me want to find more pins and restore them (and keep them out of the dumpsters).  I'm sure there are lots of pins just sitting in basements and garages, not working, owned by someone who doesn't have a clue how to fix it, and keeps telling themselves "oh, I'll get it running... someday".

Anyway, part of me says "don't get rid of your first pin, it's your FIRST".  Well honestly, evel knievel was my FIRST, this is just the first one I paid for and restored myself.  Would I sell it? Sure, but at the minimum I'd want to get back what I invested in it (including parts)

LED'S are here! LED's are here!

I'm totally digging that there are direct replacement bulbs for pinball in LED form. The bulbs mine uses is #44/47 (bayonet) bulbs, same ones you probably used in science class as a kid. Super bright, no heat, and they last a long time. Here's a photo of a few I've replaced so far, you can easily see the difference. The incandescent looks yellowish, the LED's are true white.

If your looking for LED replacements for your pinball, here's where I ordered mine (best prices I could see):
