Re: [TUHS] Bitsavers' RT/PC, AIX, AOS, etc. recent additions

It's the CMU micro kernel. The hybrid "2.6" lived on in NeXTSTEP, and OPENSTEP, with various 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 coprocoessor cards, and an OS/2 and DOS monitor program to let you boot BSD on the card. 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.
