Hi twistedsymphony! I read your post regarding the multi project. I see you are specifically looking for the Twin-16 long video board variant and the backup daughter-board to check compatibility. I currently have the short version of Cue-Brick (single PCB). I know it is not the exact long...

Great news! Your measurements are perfectly healthy and completely rule out a dead short circuit on the board. The fraction-of-a-second beep is totally normal. It’s just the capacitors on the board charging up from the multimeter's test voltage. Measuring 0.55 kΩ (550 ohms) on the 5V line with...

If the short is on the +5V line, you can ignore the audio section for now. Separate the two PCBs and measure between +5V and GND to identify which of the two boards has the short circuit. Check if there is a faint burning smell. Inspect the decoupling capacitors (ceramic disc ones) and pay...

Hello Mutawarrior, I have some of the titles you're looking for, although it will take me some time to search the warehouse and verify that they work. The most tedious part is creating a JAMMA adapter for them so I can fully test them. There are some originals, some bootlegs, and some...

Hello and welcome! Please keep us posted on your new finds and everything you learn along the way.

MB3734PS. I need this Fujitsu amplifier to repair the sound on a PCB. Thanks!

You have to look for the bootleg version; the original is encrypted.

Try this jumper configuration on the PROGTOP.

Updated list!

Hi, I received the lockbar a while ago, but surgery kept me out of business for a while and I didn't open any packages until this week. Thank you so much, everything went well! :)

I sold him a PCB and he's a pleasure to deal with; very pleasant and communicative. :)

In my opinion, they had a large stock of these memories, possibly salvaged from other PCBs, and it was more cost-effective for them to make a few daughter PCBs and use their stock instead of buying the correct memories. Throughout my time in the arcade industry, I've seen "pirate" manufacturers...
