Thanks for this post! You and I have talked about these multi game boards, but I haven’t researched it much more and had a lot of questions. I had no idea you could power the board with a standard ATX Power Supply, how cool is that? Makes the whole thing so easy!

Do you have any more details / photos of how you did the additional switches (test / service)? Where you mounted them?

You might want to look at your permalinking before too much longer…help with your seo stuff and keywords instead of the non descriptive ?p=39.

Oh, and what is the minimum Wattage for the Power Supply necessary to power that board?

I used an AT power supply. An ATX may be an issue without the ability to lock it on (unless you want a separate power button). There were no wattage specs listed in the manual that I saw. The board probably doesn’t take much power due to their size. They look very efficient. I’ll look at permalinking. I’ve wanted to do so anyway, just don’t know much about it yet.

Can you tell the difference from these 48-in-1 board and a old arcade board? I heard that game “sounds” are different on some of these newer 48-in-1 boards than from the older arcade boards.

Depends on which game it is. Most are accurate, but there are a couple that have sound issues. I think the worst is Scramble. Mr. Do is actually very good in this case!

Hi Ive just fitted one of these gameboards in an old space invaders cab, do you know of any way of inverting the rgb signal from the board so that it gives a mirrored image? All I seemed to be able to do is flip the Image with dipn switch 1

@Pickles: You should be able to swap yoke wires to accomplish this. Here is a good article from Bob Roberts explaining how this works:

Jeff you are a True God. Many thanks for responding so quickly.I read the info at I went straight outside to the gamesroom removed the yoke wire connector & cut as pre insructions, reversed the Horizontal pair and now my Space Invaders Cab plays the 48 Games perfectly whilst still using the Mirror. Top Man!

Glad to hear it. Bob Roberts is really the man! Remember his site and use it often.

I have a 48-1 in a home made cabinet using a computer moniter & a power supply 100v 7A. I plug in each seperatly & it works great. I just picked up a MR DO but it uses a 115 15A. I want to put it in like you did. Will I damage the board with a higher watt/amp rating? What power supply should I use? Thank You for this help

you should be fine with that power supply. I would recommend measuring the +5 and adjusting it to be right on +5 once you hook it up to make sure the voltage is even. Also, you may want to grab an old computer power supply and use it instead. They are cheap, and plug right into the board.
