I have a vm with NsCDE installed for when I what that childhood nostalgia hit

https://github.com/NsCDE/NsCDE

One of my mentors when I was very young gave me an Alphaserver 2100A running OpenVMS with CDE on it, and I remember using the installed scientific software (cant remember the name) to do 3D graphs, and so began a lifelong love of scientific computing!

That's heavier and lies on GTK tools to mimic the rest.

EMWM it's like a micro-CDE but without the panel, almost like the Irix interface.

And it will run really fast on ATOM n270 netbooks and the like.
