HP 715/100 10-Pin Keyboard and Mouse Pinout

[nater1217]

Hello, I just got an HP 715/100. It has the 10 Pin modular jack that requires an adapter box to use either HP-HIL or PS/2 keyboard and mouse with it.

Does anyone know the pinout of this jack, or does anyone have the A4022-62005 adapter that they could take pictures of the inside of?
I'm curious if the adapter is passive. There should be enough pins in the connector for it to be passive.

I figured this out. Hopefully this will help someone in the future. I also submitted it to pinouts.ru.
I don't have any HP-HIL devices to confirm the HIL pinout, but I'm 99% sure since I can see some data on pin 8 with a scope.

Pin Number	Pin Name	Description
1	+5V	5 volt supply for PS/2
2	M/CLK	Clock for PS/2 Mouse
3	M/Data	Data for PS/2 Mouse
4	GND	Ground
5	K/Data	Data for PS/2 Keyboard
6	K/CLK	Clock for PS/2 Keyboard
7	GND	Ground
8	HIL-OUT	HP-HIL Data Out
9	HIL-IN	HP-HIL Data In
10	+12V	12 volt supply for HP-HIL Devices

Thank you so much!
That was exactly what I needed to build a PS/2 adapter for my newly acquired 715/80.

It currently lives on a breadboard, I'll make a PCB later.
