Hi Adrian;
Somewhere in time between the higher-end series 300 and the
lower-end series 400, HP switched from 60Hz to 72Hz framebuffers
and fixed frequency monitors to go along with them. The 98752A
(one of the heaviest suckers I have ever lifted!)
and the 98789A are examples of 60Hz tubes. The A1097 and A2094
are two of the most common 72Hz monitors. If you tell me the
monitor model (framebuffer model would help too) I might be
able to find out more for you.

Hi folks,
I forgot to mention, in the crash I had last week that damaged the Apple ///
etc I also had an HP Apollo 9000/600 workstation with 19" monitor. Whilst
I'm assuming the front passenger airbag caught the monitor since it was
unrestrained on the front seat (but the seat was pushed right up to the
dash) it is now however refusing to display blue. If I remove the B plug on
the RGB cable the display doesn't alter......since if I remove the green the
sync goes and they're from a similar era could I substitute a spare DEC
VRT21 I've got lying around here in the office? That monitor is a 60hz
1280x1024 RGB sync-on-green Trinitron.
Of course, I'd like to repair the HP's monitor, but my knowledge of
repairing monitors begins at the glass fuse and ends on the high voltage bit
cheers
