There's a
guy in the UK that is selling an adaptor for PS/2 KB's/mice to
HP-HIL that is supposedly just wired through... is this
possible?!?!?! does anyone have the pinouts for the HP-HIL port?
Totally impossible [1]. The signals are not even close between the 2
interfaces.
[1] OK, somebody could make a keyboard that could work with either PS/2
or HP-HIL interfacee sgnals with just a plug change, but AFAIK HP never
did.

So what about it? It looks suspiciously like it's just a few wires. My guess
is that since he mentions it's for certain machines, that those machines have
ps/2 signals on the hp-hil connector. Any other ideas?
That's for the same machines you can plug the little HP-HIL and PS/2 box into,
just without the HP-HIL breakout.
I think what HP did was decide to use some extra pins in the RJ45-ish port to
pass PS/2 signals in addition to HP-HIL. Then they decided that might be too
confusing, so they changed the plug from "two-little-tabs-on-the-side" to
"one-little-tab-on-the-top"... because of that, this device won't plug into
a
normal hp-hip port and a normal HIL device won't plug into the port this thing
goes into.

That connector doesn't look like a HP-HIL connector. The HIL connector uses two
plastic locking tabs, one on each side of the connector. This one only has one tab and
it's on the bottom. If you look at the picture that I referenced the other day,
<http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2039310046>, you can see the
notches for the locking tabs on each side and none on the bottom (actuallyit would be on
top in this view).
My guess is that the machines that he's making thse for DO NOT use HP-HIL but
something else. Why don't you buy one and try it and let us know what you find out?
