You need a 25khz monitor. Here's a list I've compiled over the years.
25khz 640x400 SOG monitors
HP 98204A (used with 82913A 12" 640x240 and 82912A 9" 640x240 monitors)
Are you sure about that one? The HP98204A that I have gives TV rate composite
video, and those 2 monitors are re-badged NEC composite TV rate monitors
with AFAIK no internal changes.
Those two are TV rate as you say (240 lines is the giveaway). I just had them
in there to remind me what NOT to use for 25khz.
HP 98204B (used with 35721 14" 640x400 and 35731 12" 640x400 monitors)
That' the one I know. I've go the HP35731 monitor and hope never to have
to repair it agan. It is painful to work on!
I have both the 35721 and the 35731 here
to repair. Yes, the 35731 is no fun to
take apart. The late, very kind Jon
Johnston sent me the innards of a
non-working 35721 all the way from
Australia so that I could have a better
chance of repairing my own non-working
35721 (hoping for different failures in
the two, thus combined would produce a
working unit again).
