Please don't use the blue splice - that is what we call a "Kludge".

There is no hot/neutral for this particular connection and there is no reference ground. This voltage has to be measured between the two AC leads.

Curious - why are you splitting the 100VAC supply going to the DMD power?

OK, I now understand - you are using this for a 100VAC to 12VDC adapter.

Regarding the 2 pin connector above that has the purple wires (100VAC outputs from transformer) - this connection won't have a Hot versus Neutral connection at this point. But hopefully the power supply you have picked out doesn't have neutral tied to ground internally. Most modern supplies do not do have these tied together.
Also, this transformer output does not have a high amount of current output. Make sure you aren't overloading the current output from the transformer. See the fuse on the existing DMD controller for an approximation of output limit.

Absolutely sure. If you draw too much current from the 100V transformer output then you run the risk of burning up the output windings. They were fused at 3/8 amps. Based on this rating, I cannot imagine they can output much more than one amp without damage.

If you are using an inefficient linear type supply to provide power to the pin2dmd then the 3-5A load will burn your windings. But, linear supplies are not common any longer.

If you are using a switching type supply and you measured 3 to 5 amps at the pindmd then you are probably drawing less than 3-5 amps from the 100VAC source. With a 5V, 5A load then you are sourcing 25 watts. Assuming an 80% or better efficiency then you are drawing 25/.8 or about 32 watts from the source. With a 100VAC source then the current load would be about 0.31 amps.

It all depends on what power supply you are using. Who's power supply are you using?

Getting voltage from J605 will work but you just need to make sure you have the correct power supply - switching that will work with 100VAC and with 80% or better efficiency. Rare to find one that is less than 80% anylonger. A lot of the newer power supplies will work with anything from 100VAC to 240VAC.

You could also use a 220VAC to 12VDC power supply and source the voltage from the output of the AC power switch.

Does the pin2dmd have a recommended input current value or does it just list it's operating current?

You can tap off the output side of the main power switch for your 220VAC.

No way to tell anything about the 1994 power supply - it could be either. Probably about a 90% chance of being a switching supply and a 10% chance of being a linear. It would take some research to figure out which one it is. Today - you can also buy linear or switching supplies. Most people will tell you which it is along with efficiency.
One thing to consider - your 1994 power supply already has 26 year old capacitors in it.
