Re: [TUHS] pdp11 question

Just to loop things around a bit: Some of the larger VAXes used small PDP-11s (and their bastard offspring) as console processors. This started with the very first VAX, the 11/780, which used an 11/23 as a console. The console ran a stripped-down system, possibly based on RT-11 or RSX-11, I forget (and am typing this on a train in the Outer Mongolia part of Texas where it's hard to look up references). I don't know the whole list of what was used as a console for different VAXes, but I do remember that the Nautilus series (8500-8550-8700-8800) used either a Pro/350 or a Pro/380, running P/OS, which was slightly more satisfactory than the rude English non-computer expansion of PoS might imply, but only slightly. Especially for those of us who wrote code to fit into UNIX on the VAX and talk to the console processor. I also vaguely remember that although Digital were reluctant (at least early on) to make an RT-11 that would run on the Pro-series systems, someone made a UNIX for those systems. I never knew a lot about this stuff and have forgotten much of what I did know, but perhaps my words will trigger others' memories. Norman Wilson Toronto ON
