Check it out. I took a Dell M992 computer monitor and transplanted it to a standard arcade monitor frame from an Electrohome GO7-CBO.
We start by decasing the Dell M992 computer monitor.
Once the yoke, wires, and chassis are exposed, it's a good idea to disconnect the grounds, degauss coil, V and H, and the remote PCB.
I went ahead and bolted the top tube ears. This will hold the monitor at the proper level for the next step, which is bolting the bottom ears using an adapter.
I found a flat piece of metal with holes the right distance apart.
Since the 19" computer monitor tube is a little smaller than the arcade monitor tube, we have to make adapters to mount the monitor "ears" onto the Electrohome GO7-CBO frame. I used a flat metal bracket with the holes about 3/4" apart for the bottom ears. For the top ears I used left-over coin door latches with holes drilled in them.
I had to push the chassis forward as far as I could, then zip tie it in place using convenient holes and tabs.
