The summary is this: 1. Of the four operating systems once offered for the PDP-11, RSX, RT-11, RSTS, and Ultrix, Digital has discontinued only one: Ultrix (Unix). So much for Digital's commitment to Unix. 2. Berkeley 2.10 is available from UCB, IF you have an AT&T source license ($10K?) and IF you have an old, non-MSCP drive (sorry!) and IF you have a 9-track tape drive (FORGET the TK-70!). 3. Venturecom has discontinued Venix for the PDP-11. IF they had a machine, they'd sell it for around $2000. 4. uniq (1-800-DEC-UNIX) has also discontinued their PDP-11 version. They are friendly, but apologetic. My DEC salesman is seeing if they have an old Ultrix-11 tape kicking around he can offer to me without support, but it's been over a month and I haven't heard anything. So there you have it - the summary of available Unix versions for the PDP-11 is that THERE AREN'T ANY. -- Rick Rodman uunet!virtech!rickr
