		<description>And lets not forget the 6809/68000/X86 OS from Microware called OS/9. And yes it came out before Apple&#039;s OS/9, in 1980 if I remember correctly. It was a fantastic UNIX clone that was real time and could run from 2 floppy drives and 64K of ram. NASA used it on some of it&#039;s instruments.</description>

		<description>In discussions this weekend about this a former colleague reminded me that technically the first OS we had on machines we looked after weren&#039;t Unix, One was VMS and there was an IBM but technocally I don&#039;t think they let us near the operating system, all access was through a &#039;text&#039; based page based windowing system on a VT100. 

I still think we never really explored the idea of a proper distributed OS fully enough. Those multiple head nodes are really just multiple login nodes with a &#039;dumb&#039; load distribution mechamism. 

My addition to the list in the above vein would be HELIos.</description>

		<description>Several off the top of my head:

COS (Cray Operating System)
FOLKLORE
NTLSS
NCAROS
Unicos and its derivatives - Unicos/MAX, Unicos/mk, Unicos/mp
MeikOS</description>

		<description>Guy and Wayne - let&#039;s start the list. Is UNICOS dead? If so, that&#039;s my contribution.</description>

		<description>I think there are too many HPC operating systems that time has forgotten, all those unix like ports to transputers for instance that we suffered from in the 80/90s.

Whatever happened to plan9?</description>

		<description>OK John - What about the 9 (or 5 even) HPC Operating Systems that time forgot?</description>

		<description>lol @ X being &#039;an OS&#039; :-)

I&#039;ve run all of them bar CP/M and BeOS. The best bit about all this virtualisation tech that&#039;s kicking around is that you can still run many of these today, direct from your desktop!</description>
