Oh this brings back some fun memories. I worked with QNX for the ICON computer at Cemcorp and ESP Educational Software Products. The OS was so clean but it lacked a lot of basic tooling. Back then there was no GUI or even a graphics library. We had to build or port a lot of things, including a VCS, from scratch. My editor of choice was JOVE (I couldn't get Emacs to build). I remember digging up various papers on graphics and creating our first graphics library.
