Tho I did read one or two msgs somewhere that said the RD54 was somewhat reliable. In my uVAX-II there is an RD53 and a TK50 tape. The RD is controlled by an RQDX3 (M7555). I won't know its condition 'til I light 'er up later this year. Let's just hope for the best :-| However, in the uPDP-11 there is a hard disk that is not marked w/an RD- number. It is a Vertex Peripherals model V185 hung off a 3rd-party controller designated as "UDC11". What can anybody tell me about that Vertex product? Equivalent RD- number? Durability? Etc.? "Backups??!" "What's a backup?" "Why do I need to do that?" (Yes, I've heard those questions from a couple of different people over the years....) Wish I was positioned to do data recovery. I could use that to partly replace a real job as I was recently "downsized" from after over 24 years. (Today's lesson, kids, is to NOT expect to stay at a job permanently! :( ) --Chris -- -- Christian Fandt, Electronic/Electrical Historian Jamestown, NY USA Member of Antique Wireless Association URL: http://www.ggw.org/freenet/a/awa/
