HP 9000/200 (9816S) keyboard knob repair

[Paul Berger (Canada)]

I should check that bulb on my Nimitz keyboard since the dial does not work on it. I wonder if an LED would work, maybe an IR LED.

Did you happen to get any software with your 9000? HP produced a software package for the 98640A called "HP98645A Measurement Library" that would make using these cards much easier as there is no support for them built into BASIC or Pascal, which makes using the card more difficult.

For a connector I found that a Cinch 252-22-30-160 fits over the pins securely but the two outside pins, which are redundant grounds are not connected. It appears that there is also a 24 pin version.
