Offhand, some old OS would be:

	- UNIX
	- MVS
	- DOS/VE (I *think* it is still developed)
	- PSOS
	- OS/9
	- RT/11

All of those are still used, and the last two I think might even still
be maintained since they are still used in embedded systems and PDP
clones.

Do the space shuttle computers have any kind of OS?
