Hi Kevin.. I have two of them attached and working on my 11/34, and three spares and one junker for parts, as well as the complete printsets and maintenance manuals. I had to spend a lot of time troubleshooting the system last summer (as you may remember from the List... the which trouble turned out to be a reversed interconnect cable between unit 0 and the Unibus. (D'OH!!) Along the way I really got to know them. Also, Tony Duell is quite the expert on the drives, and has a lot of data on them. They're actually very tractable and easy to get along with, IMHO. Also, one can repair them with a printset, a logic probe, and a good scope if alignment be needed.. I recommend getting a dual-height Unibus extender card if you need to ever work on the Unibus modules in the drives... Let me know if I can be of any help......
