QNX is an operating system that all of us have used, but few of us realize it when we do. The OS was created in the early 1980's by QNX Software Systems, a Canadian company, but the version we are previewing today (unreleased yet, version 6.2), based on the Neutrino kernel, was pretty much (re)written from scratch some years ago. QNX is used everywhere, from VCRs, to DVDs, to medical machinery and even satellites and space shuttles. Many of you maybe even have tried the old
demodisk, a demo of the QNX4 RTOS, plus the previous version of the Photon GUI, fitting in a single 1.44 floppy. The desktop-enhanced version of
QNX RtP (free for non-commercial use) runs on almost all modern x86 CPUs, and if we judge from the following screenshots, it looks pretty good for an embedded system OS.
