Subject: ANyone have DHV11 docs?
Anyone have docs for the DHV11? Does it emulate a DH11?
(It's the Q-bus 8-line MUX)
I'd like to figure out how to tell mine what to do...
-------
I might have a DHV11 manual around, I'll have to check. I do have a
board in an old uVAX II. Do you need anything in particular? Like the
CSR and interrupt switch settings? As I recall, the Q-bus DHV isn't
quite the same as a the Unibus DH11, but it does use DMA, much faster
than a DZQ11. The DHV11 uses floating CSRs, do you know how to set
them? (I assume you are going to use VMS)
