From: Dave McGuire <mcguire at neurotica.com> I had a PDT-11/150 many years ago, mid-80s. It was kinda fun, but also kinda pointless. The only thing you can run on it is RT-11. I had one too back then and had a blast! RT-11 is terrific (infinitely better than contemporary microcomputer OSes), and anyway a 150 will run pretty much anything an 11/03 will run (but with 30 KW of memory instead of just 28) so it's really pretty flexible. I wrote a FORTH-79 system on mine (including a stand-alone 4-user version with a blinky NULJOB display on the two LEDs), and a PDP-8 cross-assembler, and one side of a two-user "pong" game that worked over the modem, and ported Small-C to it, and did a zillion other things I don't even remember. Something or other with a Microsoft serial mouse plugged into the modem port? It was such a great machine!!! John Wilson D Bit
