Hi,
I 'only' have the HP150-II. It's in a
larger case, with a 12"
CRT, an optional touchscreen (which is fitted on mine)....
I have one of these too, though without the touchscreen or any expansion
cards (it's even missing the rear plastic cover).
Seems like an interesting machine, one of these days I must get it set up;
I've only had it 9 years, LOL! How difficult are HP/IB hard drives to come
by for them (I've got the dual floppy drive unit)?
Always hankered after an original 150 though, it's a really cool shape! :-)

Hi,
I have 2 expansion cards in mine. One is the combinded parallel (printer)
port and HPIL interface. The other is 2MBytes expanded memory and an
HP-HIL port (which is disabled on a 150-II, since there's already a
built-in HP-HIL port)

The machine can run from just a floppy drive, but a hard drive is
certainly useful. How hard they are to find, I don't know. I got my
150-II with a pair of 9133s, a 9154, and a pair of 9142s (QIC tape drives).
Always hankered after an original 150 though, it's a really cool shape! :-)
I'd like one too, mostly due to the fact that the circuitry is _very_
different from that in the 150-II. I'd also like to find one of the HP12x
CP.M machines. But I wouldn't even conisder shipping one, so it would
have to be somewhere that I could collect it from.

From time to time Halted and Weird Stuff have HPIB hard disk boxes. Sometimes
they
even work!
I haven't been up there in a while so I have no idea what they have now.

I can't understand why a person will take a year or two to write a
novel when he can easily buy one for a few dollars.

~25 years ago, a student in the lab managed to get the mylar out of it's
jacket of a 5.25" diskette. Somebody asked her, "how come you didn't
realize that something was wrong when it was so hard to take apart?"
She replied, "it's just about as hard to open a bag of potato chips"

I repaired a PeeCee awhile back that belonged to a child-care center,
used by kids 5-10 years old. It kept throwing random reboots, and it
turned out it was overheating.
There were 12 or 15 CDs in the case, some on top of the CD drive and
several that had fallen down behind it. One was almost flush against
the PSU's inside vent grille.
The kids had been trying to load disks and shoving them between the
drive bezel and the drive-bay cover plate above it.

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.

As you might guess from the above, you can do that.

It's cool, ain't it?

Three months max in the office and two years in a class 1000 cleanroom.
Sucking and blowing was not good enough to clean the units out; they had
to be disassembled and cleaned out with wipes and swabs.
The 150C's had to be wiped off every few weeks or the touch feature
would get erratic.
And cleaned the internal printer without chipping the print head. Ruined
a few silent 700s learning how...
Of course, when they were opened for cleaning, we would just clean the
whole thing out and drop the really stubbornly dirty stuff in the vapor
degreaser. Better than zapping it with compressed gas.
I suppose it's better in areas where the water isn't as hard and doesn't
turn clothes washers into clothes grinders.
