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

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

The Bitsavers' RSS feed ( seemed to me to be dominated by RT, AIX, AOS (BSD for RT), etc. stuff in the last week or so. I've only sampled a few items, but discovered a few things that I should have known (or knew and forgot?) while I was at IBM. -- voice: +1.512.784.7526 e-mail: fax: +1.512.346.5240 Web: Facebook/Google/Skype/Twitter: CharlesHSauer
