HV module for use with 7JP4?

wa2ise, I remember seeing such a machine in the hospital that I worked at! Basically, you stuck a big piece of sheet film into a lower drawer that contained a crt. You were essentially making a 1:1 contact print directly onto the film. You watched the action on a live monitor that sat atop the exposure unit.

The Doc saw me reading through the manual in the break room, and commented with something like "oh yeah, that thing was a real waste of money."

Not sure if the machine used x-ray film or not, but at the time I was using x-ray film in my view cameras because I could get it from the hospital for cheap, so it certainly was sensitive to light well into the visible spectrum.
