WTB working original, not bootleg, Atari Tetris PCB.

What speed EPROMS do I need to use for this awesome hack? I can't get to my board currently to check it. Thanks! Edit, found it in the schematics.

@RealMFnG Bumping this old thread to ask a question about @Hatsune Mike 's board, which I have built out for the same purpose, to stabilize the sync on a Phoenix PCB. I have the 6.8K resistor and a 1 nF cap installed, where the silk screen erroneously has 0.1 nF and 680R values, and it works...

I really don't know. I couldn't get it to work 100% with my supergun (I tried both my Minigun and Parsec), connected to a Sony Trinitron consumer TV I modded for RGB SCART input. If I tried the composite out on the PARSEC, I got nothing on the screen as well. Using SCART on my PARSEC...

The solution was found elsewhere. The 28.636MHz crystal on the board needs to be changed out to a 26-ish MHz crystal to produce the proper H&V frequencies that most monitors expect. I changed it to 25MHz, since that's what I had on hand, and it synced perfectly.

I picked up an Ataxx board a while ago, and am putting it in a cabinet with a K7000. However, it will not sync. I am using it with the required JAMMA adapter. The board outputs both H and V negative sync, but, the JAMMA adapter seemingly provides the JAMMA negative composite sync (at least I...

@low_budget I have a v2.1 Parsec that the power switch has ceased to function. It stays ON, and the only way to power it down is to unplug the PSU. Testing the switch revealed it to be stuck always on, so I replaced the switch with a new one, but, the problem persists. Measuring voltage...

What kind of monitor do these use, and are they readily repairable? NVM: I think it's a Blast City that I'm looking at, but the labeling on the side that says "Naomi Universal Cabinet" threw me off. Either way, if the monitor in this is dead, are they readily repairable?

No worries...not interested in buying anything from overseas and having it get destroyed in shipping. Amazing, I thought threads only got derailed like this on KLOV. Still looking... US and Canada only.

WTB a fully working Rolling Thunder PCB. PM me. Thanks!

I’d leave the ATX connector on it. If you don’t want to use an ATX PSU, a high quality PicoPSU from Mini-box can be used. I’ve used it on my parsec for several years without issue.

Possibly check arcadepartsandrepair.com

Thanks, @skate323k137 !

Bump...anyone know?

Does anyone know if the battery on an Ataxx PCB can be safely removed? I can't find any information as to whether it is there simply to save settings/high scores/book keeping data, or, if it also of the same function as a Capcom/Sega/etc. "suicide" battery. Many thanks!

I am assuming the backup RAMs are the two Winbond chips in the backup section, so, I metered both at pin 28 and found that there was 2.8 volts there when powered off. Do these ICs often fail?

Yes.

Hi, I replaced the original battery with a CR2032 and did the modification to remove the charging circuitry. Prior to doing this, the system would not save settings, as the original battery was dead. It still will not save the game soft dips after modification, but, it is indeed saving the...

Does the capacitance value of the supercap have to be 100mF (millifarads), or can it be higher, like 220mF, using the same voltage rating (5.5V)?
