Awesome project thanks for sharing.

A few months ago I started on a project to make a 'grip' style chording keyboard [0] also based on the teensy, sadly the project has stalled for a bit (graduated and got a full-time).

I have the keys wired [1] but haven't figure out a nice way to mount them yet, and the firmware isn't finished.

EDIT: I always found it a bit sad that I was unable to find much documentation on how Engelbart's original chording keyboard worked, does anyone know of a source where I can read how the keys are chorded?

I received a reply on Twitter from Bill Buxton, who worked at Xerox/PARC and other cool places, pointing me at this chapter out of his book:

The section "The NLS System: Engelbart and English" contains the most detailed explanation of Engelbart's chording keyboard that I've found, and the rest of the chapter is an interesting read.
