drakar:  I added some rudimentary mouse support to this branch of the Arduino project a while ago you might be able to use as reference: https://github.com/mgrdcm/USB-NeXT-Keyboard/tree/mouse

Also this work done by a friend of mine might help:  http://andromeda.dapyr.net/~degs/nextkeyboard.html

Thanks! Already got it running though :)
It's much less sensitive than a USB mouse, the NeXT values go from about -12 to +12 and USB is -127 to +127. I put an optional sensitivity boost in which sort of helps, that's a personal preference though. People can stick with the default and adjust in their OS to get it feeling right.

Now to write firmware updaters for all of the operating systems...

This is such a cool little unit - thanks, drakar!

Unfortunately I discovered that my NeXT keyboard has a bad 'R' key, so I need to have that fixed.  I seem to recall having another one with a bad 'R' key 20+ years ago -- but I threw that one away.

Hello NeXT community:
I'm taking the connector  for test spin on my Mac mini and using it to type this as we speak ....
the mouse is a bit slow on Mac OSX High Sierra but interestingly when I launch Previous the Mouse works great https://youtu.be/MSo2lDnOrpQ,  probably just need to dial the mouse in what ever they did on previous works!

Cool stuff!

I pulled out all of my NeXT keyboards.  Turns out that one has a bad "R" key, one has a bad "." on the numeric keypad, and 3 have the L-shaped enter key.  Literally right now -- as I type this -- I am typing on my NeXT keyboard (the one with the bad numeric-keypad "." key).  I am LOVING this old keyboard, even though it is taking a little time getting used to because it has no function keys and no right control key (I use software to change the right-alt on my Macs to right-control).

Totally dig it - thanks drakar!  So so cool.  Great project!  I hope you sell bunches of these.

Hello NeXT community : They are cool, anyone know of a Mac OSX Keyboard mapper that would allow the function keys to map to or handshake with the accountants keypad keys ? Ie f1 = 1 f2 = 2 etc...

Ohhhhh..... I wonder if I could use Karabiner-Elements to remap the numeric keypad to function keys.........

Yup, Karabiner works perfectly for this.  LOVING this device more and more every day.  Thanks, drakar!!

Check out Karabiner or Karabiner-Elements (depends on what version of OS X you are using).

Hey - I just got mine and it's behaving a bit oddly for me.

When I plug it in initially, it hangs and sends a bunch of '0's to the USB, until i press a key.

Then the keyboard works, and all the keys work - but if you type any faster then super slow, it ignores the keystrokes.

And I press the command key (which maps to the windows key) - from that moment on - that is the only key that works until i unplug it and plug it back in.

any ideas? I was at first thinking my keyboard was broken - but all the keys seem to work, just slowly, and not if i press command.

It sounds like an issue with the keyboard, maybe some component has drifted out of spec over the years and is affecting the timing. Do you have another one that you can try?

Unfortunately my only other one is an ADB. I have a buddy that might have one - I'll see if he can track one down and test it with that.

Hello Jdanna: I have a known good working NeXT NON ADB keyboard that I can sell you for $25 and $19.50 Shipping USPS priority mail.    Which style of keyboard is it the L shaped or small enter key?   Best regards Rob Blessin
