I've still got a couple copies of early QNX which ran on 8088 machines,
and the upgrated "ATP" (protected) version which needed a 286. It
was a decent OS. I used QNX a LOT on a Nabu 1600 which was a non-
PC 8086 machine using serial terminals. Nabu QNX ran "bare", the
machine could also run Xenix, which required a proprietary add-in
memory management card. Early QNX was a lot lighter and faster
than Xenix.

Just this morning I picked up two more Altos 586's - which also
run Xenix on an 8086.
