The HP Computer Museum shows a picture of it but it also states "Catalog Reference: Does not appear" Maybe a prototype that was never sold?

"Catalog reference" refers to the Test and Measurement catalog which focused on test and measurement equipment and computer systems that could control that equipment.

Some computer equipment that fell outside that definition showed up in other publications like Computer Focus.

Besides the 45643A, the HP 82985A video interface and that brown 82190A ThinkJet do not appear in the T&M catalogs.
