Yep, that too.
QNX was an actual microkernel, the kernel part
neatly fit in a 4K
instruction cache. I remember Dan telling me that it worked because
only a few people were allowed to touch the actual kernel, they wanted
to keep it small and fast.
This was all pre-posix, it was Unix-like but porting stuff was much
harder than going from SunOS to IRIX.
I think that it lives on in cars, someone told me that QNX is the basis
for a lot of the car stuff. Anyone know?
Isn't it the OS of the Blackberry?
