It's the CMU micr= o kernel.  The hybrid "2.6" lived on in NeXTSTEP, and OPENSTEP, with v= arious upgrades to bring it up to OS X. 

The RT as I understand= it was a research machine, hence the BSD ports, and Mach port. 
=

What is interesting the more I dig around is that there was ROMP coprocoes= sor cards, and an OS/2 and DOS monitor program to let you boot BSD on the c= ard.  Peripheral IO was done on the x86 side. 

If RT's are = rare, I can't imagine how impossible it would be to get one of those cards!=  

The BSD assembler and linker source is in the archives too, no= doubt it'll help someone make a RT emulator.

So the 4 csrg cd set may have updates to the romp suppo= rt as it's an older version of the 5.1 kernel from 89...  Not that thi= nk there is any Mach romp users.
