Robotron:2084

[dr galaga]

Most people nowadays use a switching power supply.  Arcadeshop has a switching PS Robotron conversion (about half way down the list) for $39 (I'm pretty sure you get the adapter and PS).  The switching ones are better than just a transformer since you can adjust the output.

Thanks doc.. I'll give that a shot. It doesn't show any adapters in the photo. I'll check it out. I hope thats all that is wrong with this machine..

The Arcadeshop ps kits come with the adapter also.  The 4116 are available from arcade shop also.  I think they are like 24 bucks a set

So this takes the transformer board out, and the dc board as well. The 3 other molex connectors connect to this adaper. I'll order the ram as well. Hopefully, that'll fix the whole game... I can't wait to play this game...

If your lucky that will fix it.  You will probably end up repair all the board interconnects as well.

Another good source for parts help is Bob Roberts  http://www.therealbobroberts.net/  A old timer who knows his stuff and is about the nicest  guy in the world. 

There is a website out there that really details repair/mods to the old Williams boardsets.  I can't find the link in my piles of garbage but will look around and see if I can locate.

I went through the board connections already and reseated the wires and connectors. I hate those wire pierce connectors...

Bubba,  Here's that website.  Can download manuals, has plenty of good tech stuff also

Thanks for the info.. I can't wait to get this game running.. The more I am reading about this, the more I think these 2 items will fix everything.  I did come across some info on this UK site for using 4164 ram instead... have you ever seen it or done it? It doesn't look horrible to do...

[glassbottlesrule]

No I haven't ever seen/done the ram mod.  The other ram is still available so I've never bothered.

I am on a roll.. Robotron is working... I just got the PS and RAM... Had a few issues with, but persistence paid off. I ended up being into the game for $250 just as if I would have purchased it from the guy working.. Thanks for all the tips to get it working...
