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).
