Ultrix would be different than BSD. Ultrix was done by DEC in Merrimack (Original in TIG - Telephone Industry Group). Originally all UNIX "support" was a special for a customer - AT&T. When DEC finally decided to compete in the UNIX biz, Ultrix became a first class OS and a product. The key i

The key point for a simh person - while Mark and Bob allow you to ​put together ​ configurations in simh that may or may not have never been realized and often they will "just work" --- you really need to match not just the HW by the timeframe of the release of that HW with the timeframe of the rel

Mark is right, just RTFM. But as far as Unix goes here's a brief mix of my experience, my memory, and very quickly looking through some sources: 4.2BSD kernel conf has settings for the 780, 750, and 730, and the generic kernel ought to boot on any of those. 4.1C BSD has the same kernel conf sett

Oh, and another comment. More general, but anyway... DEC did not really expect that tapes would be booted from on VAXen, so they did not provide any standard way to boot in this way. For the VAX-11/780 for example, if you got VMS on tape, you were expected to boot a small standalone version of

Ray, not a problem. And to make it clear, yes they are instructions. However, the instructions as such are the same on the different models, and that is not the reason for the problem. However, the controllers and bus adapters themselves are different on the different models, and thus requir

Thank you Johnny. I will look for those documents. To be honest I knew that the lines of hex were instructions of course but I honestly didn't know what they were for. I only have tape experience on a then new HP/UX server and that was over 20 years ago. I would like to thank all of for your advice

Uh... The bootstrap listed there is for the 11/780. It does not work for any other model (the 11/785 is just a faster 11/780). The MtXinu manuals (do anyone have them around) had the bootstraps for tape on all the old VAXen (11/780, 11/750, 11/730 and 8600). Johnny On 2016-10-09 16:4
