It’s not their legendary boot floppy, but a QEMU image with a desktop environment for QNX 8.0, with support for self-hosted compilation, using XFCE on Wayland (sadly, their Photon UI is long gone) and providing a number of development stacks and editors. The installation process seems overly contrived (and I am not doing it this holiday season, as I have far too much to play with already), so I would have loved to see an ARM bootable image for a Pi or similar.
I’m sure some enterprising souls will hack their way through this to get it to run on bare metal somehow, since QNX has always been a fascinating RTOS (even if they lost a lot of audience to embedded Linux due to their commercial approach).
If they keep tightening the bootstrapping story, this could become a surprisingly effective bridge between “I have a QNX target” and “I can ship software on it without ritual sacrifices.”
