Does any one knows if the keyboards of the 9000/200 series are
interchangeble with the HP-150 keyboards ?

I am using the keyboard from a HP-150 II on a series 300. The keyboard has
an HP-HIL interface, model no HP 46020A. The function keys are different
from the standard keyboard on a 9826 but are
re-programmed with the
'softkeys' function.
I dont think the series 200 had the HIL interface though.

Roman,
Hil-keyboards are not the problem, the 200 series are using another type of
keyboard interface.
The Touchscreen I too they have both the same connector and both don't have
a processor on the keyboard it self.
I know the HP150 and HP239X Terminals are inter changeble, but is it also
with the 9816 or other 200 series computers ?

Well, the HP150-II and the HP9817 (9000/217) both use HP-HIL keyboards,
and those are the same.
But the original HP150 keyboard is not interchangeable with, say, the
HP9816 (9000/216) keyboard. The interface is very different. I have
schematics for both, BTW.

Hi,
the HP9816-(HP9000/216)-keyboard is definitively not HP-HIL-type.
HP-HIL is a bi-directional-bus-poll type protocol,
HP9816 is unidirectional synchronous "long shift register" type.
Here is a raw diagram of the keyboard protocol and connector
http://www.kbdbabel.org/hp9816kbd.png
http://www.kbdbabel.org/conn/kbd_connector_hp9816.png
There exists an protocol converter from the HP9816-keyboard to PS2
http://kbdbabel.cvs.sourceforge.net/kbdbabel/kbdbabel/kbdbabel-hp9816-ps2/
PS2 to HP9816 should be possible as well.

Hi,
the HP9816-(HP9000/216)-keyboard is definitively not HP-HIL-type.
But the original HP150 wasn't HP-HIL either. It was a shift-register-sort
of interface similar in concept to the HP9000/216, but different in the
details.
Onthe other hand, both the HP150-II and the HP9000/217 (HP9817) use
HP-HIL keyboards.
HP-HIL is a bi-directional-bus-poll type protocol,
HP9816 is unidirectional synchronous "long shift register" type.

'My' scrematics fotr the HP9816 should be on http://www.hpmuseum.net/
They include the 'compact' keyoard scheamtic, and it's very easy to
deduce the interface from that.
One curious thing about that compact keyboard is that the switches do not
form a scanned matrix like in most other keyboards. Instead, one side of
each swithc is grounded, the others go to a bank of 4051 (!) multiplexer
chips which select the keys (and the counter fro the twiddleknob) in turn.
There exists an protocol converter from the HP9816-keyboard to PS2
http://kbdbabel.cvs.sourceforge.net/kbdbabel/kbdbabel/kbdbabel-hp9816-ps2/
PS2 to HP9816 should be possible as well.
The reverse (PC keyboard to hp9816 host) would seem to be more useful,
given that some plastic bits in the HP keyoards are failing. Fortunately
the same keyswitch design was used by other manufacturers, so it's
possible to raid parts (my 9816 has plungers raided from a spare VT52
keyoard, even the left shift key came from there. It looks wrong, of
course, but it's the right footprint, so it fitted with no modification
and if I ever find the right keycap I can fit it).
