Adecvax.150 net.unix-wizards utzoo!decvax!shannon Wed Jan 6 10:15:12 1982 DEC DH11 on VAX - Final Answer I hope this will be the final answer to the question "do DEC DH11's work on a VAX Unibus". As Dave Martindale said, he has two DEC DH11's on his 780 and they work just fine. We have run DH11's on 780's in-house with no problems. I even think we have run them on 750's as well. The reason DH11's are not supported on the VAX is purely a marketing/maintenance/support/ verification issue. It has nothing to do with whether or not they will work in some configurations. The DEC DH11 has a bad maintenance history and is an expensive option so it was not felt to be worthwhile to take it through the system verification process to make sure it will work in all configurations, and to develop all the drivers and diagnostics for it. It was expected that it would be replaced by a better device in the near future. Unfortunately, the replacement is a bit late. So, the answer is: They do work, but don't ask for support!
