I have two 13" monitors here that used to be in Merit countertops. One has the touchscreen, and the other had it but it has been removed. I did not pull them myself.

Are they both VGA? The connectors are different on each. The Type 20 has the normal style 6-pin connector, and the Type 55 has a different type but is labeled as RGB etc. I want to use one as a test bench monitor (with a RGB-to-VGA converter), and the other as a touchscreen virtual jukebox monitor. Is there an adapter already that I can use, or do I need to hack a VGA cable?

Also, the Type 55 is missing the remote board. Obviously it won't work without it. Is it the same as the Type 20? I guess I can build one on a mini-DIY board (since it's for the test bench), right?

I know I can go over to BYOAC for instructions on getting drivers for the touchscreen monitor so that the computer works ok with it, but I want to make sure I have the means to operate the monitor.

And these are both 120v, correct?
 
Type 20 is standard resolution (CGA) only.

Type 55 is VGA resolution.

Both operate on 120 VAC and do not need isolation.
 
Hmm. Well, the type 20 has the touchscreen. Will an arcadeVGA card work to display a computer screen on here for a touchscreen jukebox?

I'll have to check the tubes, but I doubt they are the same, that I could just swap chassis' and yokes...
 
You could swap the touchscreen overlay.

Yeah, right. I tried that once and cracked the overlay. The damn things are glued on there so tight it's a pain in the ass to swap it.

No swapping tubes either. The Type 20 is an 8-pin neck, and the Type 55 is a 10-pin neck...

Then you were trying toooo hard. ;)
Generally if it has the usual double sided tape I slide a blade down through and slice the tape all the way around, then clean it off the overlay after it's off the tube.
Some new narrow 3M double sided tape applied to the overlay, "carefully" aligning it to the tube, then stick it to it. (kinda a one shot deal without having to redo the whole process)
Yes.... it can be a pain.... but doable.

Power source for the microcontroller can be a different story though, depending on where it originally got it from. (typically 12VDC, some are 5VDC) Some, especially the compact units got it from the monitor chassis, but an external source works as well.
