PS2Keyboard Library - Teensy 3.6 / LC

I've added a USB Connector to my VGA Board - Since these green PS2->USB adapters are only wires - and not really needed - this works. I've used 3.3Volt as power.
This works - but.. does it work with every PS2 Keyboard ?
Tim: If you have some room on your VGA board.. can you add a USB connector for testing ? :) I've just used Teensy pins 0 and 1

It would be really useful if Paul could say something :)
 
I pulled the badly oriented VGA connector from my PCB - when I rebuild with a fresh VGA connector I'll add a PS2 ( on pin 0&1 with 3V3 ) as I think SparkFun sent me 1 or 2 once.

Indeed that PJRC page says it works with T_3.6 - maybe the PS2 output is at 3.3V levels and Paul knows - but my quick search didn't confirm that.
 
If not, you're risking your Teensy. I'd use 3.3 volts as power if we didn't have an answer.

Searching through the net, I learned that some keyboards seem to have a pullup on the data-line. So they pull-up to 5 Volt. If that pull-up it strong enough, there's a risk for the not 5V tolerant parts in my opinion. Hopefully, users read this before they add a PS/2 keyboard.
