The speaker here. This is not QNX. This is Coherent, a Unix-like operating system from the eighties.

[rbanffy]

Sorry. Coherent and QNX happened more or less at the same time on PCs. I learned C on QNX.

Sadly, can’t fix the title at this time.

I learned it on QNX too, Burroughs ICON computer with a watcom compiler. Those computers too need to be preserved. If anyone has software for them, please upload to archive.org
