I 'only' have the HP150-II. It's in a
larger case, with a 12"
CRT, an optional touchscreen (which is fitted on mine)....
So you don't
have to vacuum out the LED/sensor array every few weeks... Nice.
A couple things about this.
One, the optional touchscreen for the 150-II doesn't have the array of
holes, it has a smooth piece of IR-transparent plastic over the LEDs
and sensors. So, you don't have to vacuum out the LED/sensor array,
just wipe it off.
Two, it took about a year or two for 150A/B in an office environment
to clog up. We had them under maintenance and the HP guy came out
with tools that sucked and blew, and with little clear plastic covers
of about 2-3mm thickness to sit over the bottom row of holes. These
matched the curve of the CRT and were molded with two pegs poking down
to sit in a couple of the LED/sensor holes. Having seen what was
done, I pestered the HP field service guy for another dozen so we
could outfit the rest of the 150A/Bs without needing to place service
calls. I'm guessing the actual HP part is somewhere between LOOK R at RE
and unobtainium now, 20 years later.
One Of These Days, I'm going to make some covers
for those holes on my 150A's
from all that vinyl packaging I've had to buy just to (try to) get the stuff
inside them.
As you might guess from the above, you can do that.
