Has anyone attempted it? I was going to try this weekend, but haven't looked into it regarding available power.

Should be fairly easy. Connect only pins 4 and 6 of the connector on the DMD and install the ribbon cable.
I've done the opposite and installed a plasma in a newer Stern.

I had to look it up. This is a Vishay. It's 6.5W max on +5Vdc.

So you would need an external supply that's capable of 1.3A. I would recommend only using a power supply with a ground pin so you can tie the supply ground to the game. You don't want the display power floating relative to the game.
Also, be careful experimenting with the Stern displays. It's not uncommon for some of the LEDs to be damaged even with normal use.
Thanks for the advice.
To update, I did this last night, and it works great. I found a 5v 2amp wall wart and wired it up to the display and used the technician AC adapter by the coin box. I did this with a Johnny Mnemonic and I think it fits the theme.

I am moving an avengers hulk green display into a cirqus Voltaire. The easier solution for me is to use the system 12v unregulated and a step down converter and pulling 5v from there. This only zaps 1/2 amp from the 12v circuit and avoids the hassles of an added power supply.

Will this work? Only connect pins 4 and 6?
So I put a stern red into a t2 without modifying anything. It's been running for a year 7 days a week. No issues at all.

It's not that it's impossible. But remember this is the same circuit that causes game resets so the last thing you want to do is tax it with another 1.3amp drain.

How did you do it?
Quoted from QuarterGrabber:How did you do it?
Literally just installed it when the original dmd died.
You guys have me wondering if there are multiple versions of the red dmd that stern released. I simply installed one a stern dmd into t2 because we put a color dmd into the stern game.

These are 5v DMDs. They'll run ok in your Williams game off the 5v but the 5v circuit is the one that the CPU logic relies upon and isn't one I would add extra strain to
Quoted from silver_spinner:Only puts strain on pre wpc 95 games. My congo runs fine with this mod as well.
The fact that the game appears to be running fine does *not* indicate that it is not putting a strain on the board circuit that wasn't designed for the extra load. WPC95 games reset just like WPC games when 5v is low.

Ok so all you did was take a stern red LED DMD, like from Xmen, and put it in a T2 without changing or doing anything? That is awesome! I am getting a ColorDMD for my Xmen and I will put the red DMD for my Xmen into my Dr. who 
Thanks for the advice!

I am not recommending anyone else do it. Per this thread it seems that maybe I got lucky with no issues. I have had it in a T2 at Headquarters running fine for over a year though. I just don't want to see anyone do something because I got lucky and end up damaging something.
Quoted from markmon:For anyone doing this I would recommend at least getting that wpc reset board that uses the 12v for 5v on the CPU side
Where do you get this board?

Sweet, thanks man! That's way easier then splicing this and wiring that.

Ok I have been reading this three and thinking about installing the red stern dmd that came with my NIB met pro earlier this year in my T2. Is it as simple as buying the $29 reset board mentioned by markmon and installing it? The reason I am asking this question again is that I know there are a lot more red stern DMDs out there with color DMD getting more popular and wonder if this has worked for others and/or if someone has discovered a better option. Thanks.

Quoted from tomh52722:Would this do the same thing?

No it won’t. Get the reset board Markmon mentioned, a step down converter, or a wall wort.

Yes, found an old Roku wall wart that did 5v and 1.5a, pinned a connector, looks great on my T2. Thanks Pinsiders!
