For those of you interested in getting a replica of NLS/Augment, there's a windows program that mimics it pretty well: http://www.ndma.com/resources/ndm8543.htm

A one-handed "keyset" is also available here for those of you who want to experience NLS the "engelbartian-way": https://www.infogrip.com/bat-keyboard.html

Unfortunately, the software was written in the early 90's and it's only 32-bit so you have to run it in an emulator to make it work on modern systems.

It's a real shame that NLS didn't catch on. The big issue with it is that it's like emacs in a sense - there's a learning curve involved in using it which makes it intimidating to use. This makes it hard to market to commercial markets (lotus notes took over in the '90s). It's too bad they didn't open source this back in the '70s, this is a "could have been" software project.
