I always wonder about Apple Extended Keyboard II with white switch.
I was little bit disappointed by Dell AT101 so I wanted to get white slider or if AEK II is so good then I would buy adb-usb converter to use.
so, I read ALPS wiki trying not to get MITSUMI switch instead. and hit ebay for right keyboard..
I knew this keyboard would be non-clicky but tactile real complicated ALPS keyboard.
after few days I got M3501 with the serial number ending with M0312. I was so sure this is what I wanted.. and what do I have?
The keyboard has very little or no tactile bump at all- OMG

why..? I guess that this is because of the years and years of abuse. I think this particular keyboard is a school survivor
Lesson learned: Do not expect the average condition when you deal with a school item recycler.
only good thing about this keyboard is damped slider - very soft bottoming out. hmm.. next project would be apply this sliders to Dell AT101w.
