This is the same form factor as the composite version, either a type RHA or RHB. Perhaps an RHN? Give me a few days and I''ll dig into my Conrac file.

The horizontal frequency would have not been much higher than standard NTSC, and as Wayne suggests, it came with stable black level circuitry and a controlled phosphor CRT, probably made by RCA.

The composite models had a notch decoder; the model after this had an optional comb filter decoder.

Conrac made "computer" monitors for higher scan rates-the QQA (monochrome) and the 7211 color model.

That was many moons ago..
