Weirdly enough one of the problems in my Game has when it starts to do weird shit it starts adding credits on its own

This is Mike’s response from Vlabs The G80 power supply is intended for Sega Gremlin VECTOR games only. I have not tested it in a Astro Blaster game, although there is a small 8pin (555 timer) chip on the power supply board that simulates the 60hz ac signal which is used by the G80 system in...

I’m pretty sure that is 100% correct in fact Matt J who looked at my boards twice used his Star Trek cage to power my boards with a monitor from another game sitting on the floor that was roster

I tried rebuilding it. I recapped it reload. It was testing it, but for whatever reason it intermittently does weird stuff. I’ve had my game boards looked at twice and they say it’s not the game boards that are the problem. It’s your power supply. I’ve tried two different power supplies a power...

I found out the hard way that this adapter is only for vector games and not raster. Why that matters I do not know.. but I got through to Vlabs and they say it’s not ment for my machine. So it’s sitting on a shelf someplace.

I’ve secretly wished that some how a darksoft kit would be made to run both vol 1-2 on 1 PCB

Do you know what ATX power supply that used by chance? I’m curious what the -12 MA rating on your supply was. I understand you don’t prefer the VL set up but I just looking for information on what others are using that are intact using them.. thank you.. I don’t need a reminder that the...

So thanks for suggestions but I’ve already purchased the replacement and was looking for others that also have and use them. I’m looking specifically for the supply they are running with the adapter.

I’ve looked all over but it’s difficult to locate the -12 @800ma/.8a. Most are @300ma/.3a - many at @500ma/.5a. I can’t find a @800ma. What are people using and where can I locate. I’ve been looking on eBay and Amazon and google, haven’t uncovered anything yet.. I’ll keep looking but I thought I...

I did this to my DK3 , i cant remember but i think its was just the LM3900 chip that i sent backwards power to. it was pretty easy to spot, it was blown out. i followed the traces to it, but DK is different than DK3

I would unplug all of the expensive stuff like your PCB and anything else that could be damaged as a result of incorrect voltage is being sent out get your volt meter out test the voltage on those wires and Continuity to all the other pins just as a jump off.. It's been my experienc that...

I’ve looked high and low. I know they were reproduced in limited numbers, but that has passed. I acquired a the game, which need a few repairs. The header on the optic was cold and loose, I repaired that and it works now but sometimes the rotation sticks slightly, I took it apart to to identify...

Close, if the roller popped off it probably would work. I’ll check and see if they others thank you, I didn’t think to check there. I found a couple on Amazon but I wanted a quality product but I did see these

Looking for some replacement micro switches that are on this mini universal joystick. It's installed in my Mr Do kit. I'm looking around for possible options. They are much smaller than the Nintendo style, I have these in my stash.. Possible source for Some replacements?

all great information, going to find a manual...

CUSTOM IC MB14257 IC25 says it’s a custom, on mine it looks pretty bad.. kinda afraid to mess with it.. but I wonder are these obtainable? I’ve looked all over for one googling different terms and I can’t seem to locate anything about it or find a replacement…

They are marked on the chip and PCB for orientation, I understand what you’re saying, thank you I appreciate it

Thank you so much for advice. I’ve been looking at the video PCB layout and list, maybe I’m missing something. These types of repairs are not my level, but if you could point out the location and the Type of RAM in the list I can surely give it a shot.. This is the video PCB you mentioned 6...

AIve tried reseating all socketed chips, cleaning edge connectors, checking voltages, reflowed the fiilter board. Games boots and plays, but it has a small graphical issue with the numbers and score. Ive looked around for resources and repair logs, somebody who might could take a look at it. May...

Still stuck on erasing flash please wait? Is this normal?
