I was at the Valley of Fire park outside of Las Vegas today and saw a petrified log. But more interesting to me was the sticker on the fence. Look at the left side of the pic. Who would put that there??????

I hoped to restore this over the summer but couldn’t make the time. I’d rather not have it sit in an unheated garage all winter so I’m selling a grail … original Tailgunner. The game doesn’t work. Tube appears fine but the chassis has some burned components and would need a rebuild. Game PCB...

I'm selling a repaired and fully working Centipede PCB. Washed, repaired, deoxit on all socketed legs. Overall it's a pretty clean board with no repairs on the edge connectors. Tested with multiple on/off cycles but a minimum of 24 hours on. This has a chipped ROM but I pulled it and it tested...

I’ve got a board with one remaining problem I can’t solve. Everything works fine except the archer immediately moves upward on player 1 only. Player 2 is OK (I don’t have my bench wired for upright so it flips screen orientation like a cocktail and chooses the second set of trackball inputs)...

I have two boards that are acting similarly and I’m stumped. Self test indicates ram issues (high beeps on certain chips) and I swap that ram out but the problems remain. High beep on chip 3, replace. Then high beep on 4, replace. Then high beep on 3 again. Two boards are doing this. They...

I lightly restored this Rockola cabinet. Front, top and back repainted. New CPO, rebuilt joystick. Monitor recapped and a new tube installed since the old one was burned heavily. It's a K4600. New t molding. Side art is only cleaned up, it is original. Plays as it should, has an Eyes PCB in...

I've been working on a couple Defender boards and wanted to use my FlukeEmu and 6809 pod to verify ROMs in circuit. Took a while to sort through the bank switching, especially since Defender is different from other Williams boards related to banking ROMs. The address to write to is D000 (not...

I have both an HP 10529a and a BugTrap 20 pin version. I’ve not found them to be consistent but I’m guessing it’s me and not the tools. They sure seem simple enough. But then I saw this post from Brian B, posted years ago, that gave some good insight. Especially point #3. I’m sharing to...

Doesn’t seem like much but I don’t know if this will spread. Do I fix it or leave it alone?

I bought a parts board from @64B1T thinking maybe I could salvage a few parts. His listing said something like "most certainly would catch your machine on fire" if you tried plugging it in. On inspection, this board somehow got tarred. Rocks, hay, sticks and shards of glass all mushed into the...

I have a pod that is supposedly good, but doesn’t work with my FlukeEmu. Want to plug this into an original mainframe just to see if it passes self-test. Thanks!

...wasn’t definitive but I was pretty sure. Reflowed the pins, no change. I then pulled it. It tested good. I replaced it anyway and the problem was *mostly* gone. M6 is a similar chip and looked just about as rusted. I pulled it, legs fell off. Replaced that and the ram tests were successful...

Refurbed and tested for more than 24 hours. New ROMs. Replaced the round filter caps with modern equivalents. Edge connector was previously repaired and looks good. Crystal had missing solder pads, kynar wire added between pins for a solid connection. $275 shipped to continental US. SOLD

Both got baked at 400F. Nuggets get 20 minutes. Pokeys only got 5 mins. Nuggets came out great … pokeys, we will see …..

For most folks, this is a hobby. But with new IRS rules for 2025, if you sell $2500 and get the money via eBay or PayPal, you’ll get a 1099. Does it change how you price things...

I need some suggestions, this one is strange to me. Test mode indicates bad ram 3 and 8, sometimes also chip 7. These have been socketed, I swap them with rams from a working board and get the same errors. Fluke cannot consistently get through a RAM SHORT test. I took note of these errors...

Is anyone using AI to help troubleshoot arcade stuff? I'm using it for a few things and have been pretty impressed, although it definitely gets some things wrong. Mostly, it doesn't get spefic chip locations or pin assignments right without some back and forth. But for ideas on where to start...

Any recommendations on a good box for shipping PCBs? Especially Atari which are a little longer than most. I have a Fellowes 25x13x3 that is just perfect. Strong and fits just right. But I can't find those anymore and most boxes end up being way taller than needed. I hate sending a bigger than...

$20 shipped in the US. If you are elsewhere, let's talk about shipping. If you are in Canada, I will make it a good price because, well, some of us aren't feeling very good about the sh!t happening these days. Y'all deserve a break.
