It has never been clear to me whether those adapter boxes actually do
what you would want to do here, i.e. allow you to plug a PS/2 keyboard
and/or mouse into an HP-HIL host port and allow the PS/2 devices to
function as native HP-HIL devices.

Some references on the net indicate that at least some of those
adapter boxes were really just passive breakout boxes where the host
natively supported both HP-HIL and PS/2 protocols but just had a
proprietary connector that needed to be broken out into HP-HIL and
PS/2 connectors.
