As for Ultrix being discontinued because the PDP-11 is an "old machine": My PDP-11/73 is about 3 years old. It is, in fact, the newest computer I own. DEC just introduced two new models, the 11/93 and 11/94. So, the discontinuation of Unix cannot be justified by oldness of model. No, IMHO the discontinuation of Ultrix was because a PDP-11 with Ultrix was not competitive price/performance with other Unix boxes. One must always remember that Open Systems means that you can lose business to competitors. While, of course, when customers are locked in to RSX or RT-11, they can't get away. Ken has a good point about MicroVAX IIs being cheap (so to speak), and my latest idea is to get a bare-bones MicroVAX and move the 11/73's peripherals over to it, then sell the remainder to a spare parts dealer. I share Ted Nelson's sadness about the DEC that was - and the DEC that is today. Alas. -- Rick Rodman uunet!virtech!rickr

Can someone point to where I might obtain a version of UNIX or a UNIX derivative for a PDP-11? thanks, Russ Cook rcook@pk705vma.iinus1.ibm.com

The first is UNIX 2.10BSD, which is real BSD UNIX, basically the same as 4.3BSD. It is available from USENIX in Berkeley, (415) 528-8649. It only cost us $200 for the media, a TS-11 tape, but we had to prove that we already had a site license with ATT for UNIX. It only comes with installation instructions. You have to purchase the 4.3BSD documentation seperately if you want it. It seems to run fairly well except the network stuff seems a little slow. I don't really use the network stuff. THe second is VENIX (Release D I think), which is a clone. It is available from VenturCom in Cambridge, MA, (617) 661-1230. I am pretty sure they don't support it anymore but they still may sell it. We have been using it for quite a while (> 7 years) and it seems to work pretty well. It doesn't include any network stuff, but does support standard peripherals. We have done alot of patching to the kernal over the years, so if you get it and need some help drop me a note. By the way, UNIX 2.10BSD comes with the complete source code for UNIX, which I have found great to have access to although it is 70 Mb worth of stuff. Hope this helps.

Seriously though, 1. Try AT&T - they started it all. 2. Try ULTRIX-11 from Digital - they always change the name or do something to confuse the user. Support may be hard to get today. 3. You could try your local DECUS office - there are some ULTRIX utilities in the DECUS Library but as yet Digital has not donated ULTRIX-11 as far as I know - maybe we should encourage them.
