Eric is correct. The keyboards use HP-HIL and not HP-IL. They're two completely
different things. I don't know how it got started but a lot of E-bay sellers list
HP_HIL devices and call them HP-IL. HP-HIL is used for operator input devices; keyboards,
mice, tablets, numeric keypads, etc. HP-IL is a two wire serial version of HP-IB and it
used for peripheral interfaces to things like cassette drives, some meters, O-scopes,
logic analyzers, printers, etc. It has never been used for any keyboards, mice or related
items to my knowledge.
You might try searching E-bay for "HP-IL" and find a keyboard and/or mouse.
They're quite common. Bear in mind that if it's a keyboard or similar device they
will be HP-HIL even if the seller claims it's HP-IL. As you noted, HP-HIL uses the
RJ-45 ish connector. Usually there will be two sockets close together so that you can
daisy chain other HP-HIL devices to it. The connectors and sockets are identified by one
or two dots or raised dimple so that's another way to identify them. The dots are used
to idetify which socket to plug additional devices into. Plug the connector with a single
dot into the socket with a single dot, ditto for items with two dots.

need to know what sort of KB it uses, it looks like a
funky RJ-45 ish

It's called HPIL I think .. HP Interface loop. You can find these on
eBay of from collectors that have excess stock :).
