I recreated that in grad school, also using QNX. We set it up to run a paging (POCSAG) system that you could put the floppy into any computer, hook up a DSP board and modulator, reboot the machine and you'd have a paging system. My advisor showed it to Andrew Viterbi, and got us grant.

When I went to recreate it, I contacted QNX and asked if I could speak to the guy who did the work, and he had died the year before. So, I just took apart his floppy, and figured out how he did it.

The things you can do when you invest your time 100% in something.

Yup, that felt incredible even at the time, let alone now.

What's this? Now I want to know.
