Who else here survived the 5.x era? Bonus points if you used and thought it was magic.

Just fired up an old project image from the early 2000s – , Tornado 2.2, and a Pentium-based SBC.

#EmbeddedSystems #RTOS #VxWorks #LegacyCode Did you know? VxWorks 5.4.2 (and earlier) used the wind kernel – a single flat address space, ring 0 only. Every task could see and corrupt every other task’s memory. But you could hot-patch functions live in the shell with just: Pick the tone you need

No MMU protection. No POSIX threads. But deterministic scheduling you could bet a Mars rover on.

If you ever debugged a priority inversion with wind in Tornado 2.2 – you have my respect.
