Hmm, we've got two or three HP terminals with the touchscreen option;
Hans Pufal was over last weekend and pointed them out (we've got a big
stack of HP terminals which I've had time to sort into piles by model
number but never do anything else with).
I'll have a look if I get a chance and see what the model number is for
these (and what connectors they have).
cheers

It was also a option in one of the terminals but I forget which one. I
have a loose board of LED/Phototransistors that I found was used to
retrofit Touchscreen capability into one of the terminals.
I once saw an HP monitor with a pair of HP-HIL connectors on the back...
Intrigued, I waited for the 'owner' (actually user) to leave, and then
cautiously pulled the case. It turned out it could take the same
touchscreen option as the HP150-II, and that these were the connectors
for that. I think I
have the touchscreen frame from one of those, 4 circuit
boards linked together in a box, with a lots of LEDs and
phototransistors. Always been curious what it came out of.
Quite possibly, that's how the touchscreen worked on the 150.
