Hi,
This guy:
Isn't just about everybody who has a 9915 looking for one?
I have the pinout of the keyboard connector on the 9915. The keyboard
matrix is the same as for the HP85 (and the service manual for that is
on the MoHPC CD-ROM). It is just a matrix of switches (OK, shift, ctrl,
caps lock are outside the main matrix, if you see what I mean), and a
speaker. No active components.
I am thinking of 3 solutions :
1) Find a broken 85, raid the keyboard, wire it to a DB25. Problem is
that HP stuff rarely dies...
2) Wire up a matrix of switches.
3) Make an interface (microcontroller + a few ICs) to like a PC/AT
keyboard to the 9915. Probably the best solution, but the most work.

is looking for a 09915-68000 keyboard (aka HP 98155A),
probably as used with an HP 9915 computer.
