has anyone got a copy ( that can be downloaded) of the user manual for my
old hp141t..cant seem to get the storage bity working..all else ok..i
think...
any repair mods whatso ever would be useful...

as screen intensity seems to be fading, needs to be up 3/4 before visable,
at full on is quite bright, but seems to be less after trying to get storage
to work!!just got a REALLY flooded bright screen when switching to storage,
but no trace, just like someone had thrown a bucket of luminous green paint
on the screen which slowly ran down the screen!!
any ideas??

thanks simon g0zen

there were so many of these built that you should be able to get a manual
from www.w7fg.com

There's a US Army site containing lots of scanned downloadable manuals
for test equipment of this vintage... but I've lost the URL - can anyone
help, please?

Daft as it seems, that actually sounds quite promising! I thought my
tube was dying too, until someone showed me how to set up storage mode.

The optimum intensity setting in storage mode is lower than in normal
mode, and the setting is *very* critical to get a clear and visible
trace with no flare. It should be just below the point where the
background intensity starts to increase very rapidly... but a gnat's
whisker below that, the trace itself is too dim to see! You'll never get
the same contrast between a bright trace and dead-black background that
you do in normal mode.

Keep on experimenting, and you may well find it's OK.
