Adobe Illustrator doesn't support HPGL, I will be providing the Illustrator files however. The Illustrator file format is backwards compatible too which is good.
I'm still working on things, I might need to start a webpage where I can put all of these files for easy access.
Thanks everyone,

Here's an update, I may or may not be joking about the semi-literal Hi-Z/Lo-Z interpretation
