Hi Jerry:
Is there an HP Journal or other article that goes into detail on how
they did that?
Have Fun,

Just a quick note...
HP was quite proud that scales for their precision meters were individually
produced
for each movement on a custom made servo controlled photographic calibrator.
An archive might be nice but won't provide the meter accuracy of the originals
produced
for each unit.

Didier, Its subjective then. If its bad enough you take the risk because you
do know the process
will degrade the scale. Essentially when its time to do it you will. So the
good news is this.
With todays tools you can very accurately reproduce the meter scale. I scan
them at 1200 dpi as
I just did for the dymec. I prefer bitmap over jpeg for storing them.
Additionally with the
various paint programs that seem to come on every pc today you can always fix
issues pretty easily.
Then print to your favorite material which most likely is a white picture
material. (I like it
because its a bit thicker and more stable) Though good quality paper is
excellent also.
Hmmm maybe we should send our meter scans to K4BB repository. Heck he has rom
images.
Regards Paul.
