The stripes are early Williams – you can see them on the Stargate instruction manual. So, what are they made of? It sounds like they're not stencilled. It would be nice if someone could repro them.

PM sent about a Stargate part.

I also bought one of those crimpers based on Dokert's recommendation! It's a great tool. Other than that, I love my no-name Hakko-clone soldering station, my Hakko 808, and my HP logic tools (probe, pulser, current tracer, and clip, though I have yet to use the tracer). I recently also picked up...

Nice carpet, Tok! Yeah, I've seen plenty of pictures of Williams games where ops put squares of replacement grill over the speaker. Must have been lots of people out there who would put their fist straight up through the grill when they got too excited.

Okay, this is for those who have used Valspar's Weathered Fossil and Pewter Lustre paints for a Robotron restoration. Am I right in thinking that the Weathered Fossil is just a basic grey paint and the Pewter Lustre is a clear metallic finish? Or is Pewter Lustre grey in colour too? If you...

Randy just says that the bad circuits show a much lower junction drop than the others. In his video, most show around 0.5 but then a bad one shows 0.17. The ground pin will show a short, of course, because you've grounded the other lead and the power pin will show a low reading, so ignore...

The videos are great. As far as I can see, he's posted most, if not all, of the series that occasionally come up for sale on this forum (though he may have edited the YouTube copies). As I said, most of the videogame ones are old, but then the games are old, so that doesn't matter to me. A lot...

I'm only learning, so please don't shoot the messenger if there are problems with this, but I've been watching Randy Fromm's videos on YouTube and in his "Basic Videogame Troubleshooting" he suggests putting the multimeter on diode test, grounding the red lead and running the black lead across...

What's the reason for putting one of these in a home arcade machine? I can understand why they were originally put in for machines that were in commercial use but they look pretty ugly for a home machine. And do home users still come across the problem this is there to prevent? To me, it would...

I don't understand this bit:

I'm interested in Defender, Robotron and Stargate sheets, if anyone has originals for sale. As for repros, a lot of it is reproduced in the drawing manuals, so you could piece most of one together. I have the Defender sheet that someone scanned in while back but it's in two parts. If anyone...

Not that I think anything he wrote could qualify as a thesis, but I think MTPPC thought he was advancing more than one thesis, thus "theses".

Until she reads this thread that is …

That's because they're laughable. Reducing complex situations down to bumper sticker slogans and then impugning one serviceman from the safety of your computer is just offensive.

Looks like the sort of thing that was added after the problem cropped up in the field. "How can we fix this? I know, let's just screw a block of wood there."

I know that jrok's board uses a 6809 and that it's not emulation, but do the games play exactly the same as the originals? For example, can you still get Defender to freeze if you pick up all the men and then place them all down while not moving forward or backward? And do aliens still bleed off...

It looks like you've done a really nice job so far. Keep going and you'll have a great game you can be really proud of.

Plenty of time to have been testing it then! I'm glad you got it, and at a reasonable price. I've got a couple of HP logic clips and the HP comparator, but the Fluke combines the two. You should scan the manuals and post them on the manuals page.

Have you tried it yet? And did it come with the pins or are you going to have to make them yourself?
