I picked up this 26" NEC monitor in the late 90's, I'm thinking 1998/99. I traded the guy a Tempest spinner for it. So at that time it seemed an even trade, probably around $40. It has a manufacturer's date of April 1988.

I stashed it out in the barn and forgot about it for 25 years. Until yesterday.

I think these monitors were most likely used in trade shows or the like back then. It doesn't have a RF tuner or anything like that, it only has video/audio I/O.

I see it has this 34-pin RGB connector, so after poking around for a bit, I figured out where the actual RGBS pins are.

So I fabri-cobbled together an old floppy drive cable and jamma harness to a TPG... This monitor actually works!

Does anyone know what a VTR connector is? Base on the vintage of this monitor, I'm thinking it means Video Tape Recorder? Would this be a NEC proprietary or Japanese connector? I haven't seen this before.

I have an NEC monitor set like this too. They are good for console games. The VTR cable is nothing special, from what I've gathered it is just composite video with one audio channel with a passthrough. I had made a pcb a while ago to break out the jacks into BNC, but it's not a great design. I should redo it...
 
Those connectors are also on the back of some of the Sony Laserdisc Players from the 90s. I checked my Stack-O-Laserdisc Players and found that connector on the LDP-1450, LDP-1550 and LDP-2000 players, all of them labeled "TV". I'm assuming they are Japanese specific since I don't recall ever seeing them used here in the US, just like SCART connectors were mainly used over in Europe.

It's a quite old standard for professional equipment that found its way into pro-sumer equipment like early VCRs and LD players back in the day. Some high end consumer TVs supported the VTR connector format but most just used the now common composite video RCA jacks.

The VTR connector allows pass through connections (daisy chains) for composite video and mono audio signals.

Yeah, just what I guessed, a video tape recorder connector. Not all that useful, to me anyway.

What is nice is the RGBS input.

It syncs right up with boards, no fussing around.
