I am considering porting a laboratory automation system currently running
on a pdp11/73 under a custom version of Unix V6/7 to the 386/486 under QNX.
We need times from interrupt to execution of user code on the order of
50usec typical.  I understand that QNX can do this on a 25MHz 386, though
I havent measured it.  I would appreciate hearing any feedback from
people using QNX in similar circumstances.  Please respond to me directly
at address uunet!lsr-vax!art.
