In this video, you'll see a Burroughs ICON (a.k.a. Unisys ICON) boot the QNX operating system from across an ARCNET network from a LEXICON file server. Next, we'll log into the system as root and explore some of the features of early QNX. You can learn more about this system here: https://jasoneckert.github.io/myblog/...
Errata: I mistakenly said during the video that you could connect up to 16 ICONs to a single LEXICON. I should have instead said that you can connect up to 32 ICONs to a single LEXICON.
