Hazeltine 1500 screen garbage; ideas?

Thanks to the generosity of Kenneth Marshall and his colleagues at the
Laboratory for Laser Energetics, I now have a MicroPDP-11, RX-01, a
whole box of miscellaneous flip chips, tons of documentation, and a
Hazeltine 1500 terminal. Preliminary to setting up all the rest, I
thought I'd try getting the Hazeltine working. I plugged it in and
powered up, but the screen seems to be displaying random characters
constantly while flickering... it's like somebody is sending a binary
file over the serial line, except the serial line isn't connected to
anything. Can someone with more terminal knowledge than me try to shed
some light? I'm going to check very carefully to make sure no keys are
sticking now... I don't think that's the problem but it sure would be
nice if it was :)
