I still much prefer big old CRTs to modern LCD
displays, and it's rare that
there's not a stack of stuff parked on the top edge of the case. :-)
One of the gret things abotu the HP9836 machines was that the monitor has
a large flat top and that there were no cooling vats on it. And being an
HP it was solid.
You could happly put a dot matrix printer or pen plotter on top of that
monitor when the system was in use.
