To anyone interested in getting a real Plasma DMD working, here's the info I put together in another forum:

Here are some examples of my build running an original, unsegmented, plasma DMD. Watch it in HD:

Credits go to Zebulon, Russ and RoccoC.

Here's what you will need:
1) Power Supply Board - to convert the transformer AC voltages to the DC voltages required by the display.
Best options available:
a) DMD Piggy (around $40.00): http://www.pinballlife.com/index.php?p=product&id=2828
b) Rottendog (around $90.00): http://bayareaamusements.com/Merchant2/merchant.mvc?Store_Code=BAA&Screen=PROD&Product_Code=PC-A-14039R
c) Zebulon's DMD Power Board (prototype phase - around $50.00 when released): http://zebsboards.com/index.php/coming-soon/2-uncategorised/3-available-third-quarter-2013

2) Transformer - The power supply requires inputs of 80VAC and 100VAC. You can either use two separate transformers for this, or use a single dual output transformer. The user "RoccoC" at VP Forums is putting a 20-units order together to save money, so if you're interested make sure to post on this thread saying so. It should run at about $35.00 or so for a two-in-one input 80VAC/100VAC, output 120VAC transformer.

3) ATX PSU - The power supply board also needs 12VDC and 5VDC. I'm using a common ATX power supply for this, but you may be able to use separate supplies if necessary.
An option that I found is a separated PSU that should work and it's very cheap (around $10.00): http://www.amazon.com/Coolerguys-100-240v-Molex-Power-Adapter/dp/B000MGG6SC/ref=sr_1_1?ie=UTF8&qid=1371544026&sr=8-1&keywords=12+power+supply+molex

4) Necessary connectors:

http://www.pinballlife.com/index.php?p=product&id=1599 (x1)
http://www.pinballlife.com/index.php?p=product&id=1597 (x1)
5) Colored wires for easy identification: black, red, yellow, purple, blue

6) pinDMD control board: brilliant product from RussDX, this board is the interface between your computer/emulator and the PLASMA/LED DMD Display (around $90.00): http://www.pindmd.com/default.php

7) Vishay Plasma DMD (around $160.00): http://www.pinballlife.com/index.php?p=product&id=164
About $180.00 from here (3 available): http://www.ebay.com/itm/New-Pinball-Machine-128-X-32-Dot-Matrix-Plasma-Display-Vishay-Dale-/161044080029?pt=LH_DefaultDomain_0&hash=item257ef9a59d

Here's the wiring diagram (independently of the driver board used, J604, J605 and J606 will be present and the wiring should be done the same way):

Here's what I gathered as some of the main differences between LED and PLASMA DMDs:
Quote:
LED DMDs:
The best: Vishay (other brands available, most segmented, meaning empty visible lines running across the display)
DMD Price LEE-128G032B (segmented - the cheapest): $279.95
DMD Price LEE-128G032-1 (unsegmented - the closest to a plasma): $543.89
How it's driven: pinDMD2
Power Source: pinDMD2 via USB
Voltage: 5v
pinDMD2 Price: $89.95
Look: looks good, sometimes too bright or not as bright as the plasmas, just different. It has visible segments (unless you spend a lot of money on the unsegmented version). Not quite the same as the original plasmas if you're looking for the "authentic look".
Footprint: very little, basically just the DMD, the very tiny pinDMD2 and an USB cable.
Life span: very long

Total cost: $369.90 (with segmented LED - 8x8 LED light blocks, meaning visible lines)
Total cost: $633.84 (with unsegmented LED - evenly spaced LED lights, like the plasmas)

Quote:
Plasma DMDs:
The best: Vishay
DMD Price: $159.95
How it's driven: pinDMD2
Power Source: Computer PSU + 2 transformers + Display Power Board
Cost of both transformers (120v to 100v and 120v to 80v): $40.00
Cost of the Power Board: $39.95
Voltages: 100v, 80v, 12v, 5v
pinDMD2 Price: $89.95
Look: doesn't get any better than this. It's the original display used in dozens of machines.
Footprint: needs additional space for both transformers, the display power board and extra wiring. The 120v to 100v plugs directly to the outlet, so in reality you just need extra space for the 120v to 80v transformer+case and the display power board. These are the dimensions of the transformer, so make sure you have space in the cab: 3.25" (L) x 2.1" (W) x 1.94" (H)
Life span: long, around 12 years or more (I believe the one in my Monster Bash is original and the machine is about 15 years old. Still looks great)

Total cost: $329.85 (+fuse and other minor electronic parts for extra safety)

At the end you saved about $40 in relation to the cheapest, segmented LED display, but you saved a whooping $303.99 in relation to an unsegmented LED display and you got a display that looks and feels like the original ones, because it IS an original display. More headache? Definitely! Not as clean and also got some high voltages introduced to your cab. But if you are a pinball owner already, as I am, I'm pretty aware of the high voltage running in my pinball already ;)
Besides, where's the fun without a good little challenge? :)

If you're trying to get the best of both worlds, than you can get a real Vishay plasma DMD 12v with an integrated power supply for about $475.05 from uk.mouser.com
Add to that the price of the pinDMD2 and you got to $565.00 (!!!)

This is incredibly well done, and a great piece of information.

Thank you for sharing!
