...
   For the
uninitated on Classiccmp, this is a 68000-based 
 computer (OK, there was a very late version with a 68010 in 
 it...). It's a desktop machine with a built-in keyboard   
 Not always I mine has a separated keyboard (photo at www.hpmuseum.net) 
And this is an 9836? Original HP? I have never heard of that version.

What is the interface between the keyboard and the rest of the machine? 
The all-in-one 9836's keyboard is lust a matrix of switches (and a rotary 
encoder for the twiddleknob) with a 34 way ribbon cable linking it to the 
motherboard. The motherboard cotnains an 8041 microcontroller adn a bit 
of TTL to scna the keyboard.

Of course other machines in the 9000/200 family used either a custom 
serial interface for the keyboard (HP9816) or HP-HIL (HP9817).

Waht dows your separate-keyboard 9836 use?
