Ok, back in the day, when the arcade game was very popular, they used to put a second monitor on top of the cabinet so people could spectate easily. My question is, how did they interface it? Did they simply splice into the Jamma harness's video wires and run them to each monitor, or did they have a splitter of some kind?
The reason I am asking is because I wanted to re-create this type of setup on my MK1 and snap some pictures for the 20th anniversary of MK. I have extra monitors and building a box and replicating the look is the easy part, but I'm not sure how to go about hooking both monitors up at the same time. Don't want to damage anything.
