I have a PDP-11/83 with an RQDX3 disk controller and a pair of RD53
drives from a MicroVAX II. Since all I can get from both drives are I/O
errors, I am left to assume that they were once hooked to an RQDX2
controller and now need to be re-low-level formatted to work with the
RQDX3. Does anyone know what is required to do this on an 11/83? Was
there an XXDP diagnostic program that did this?
Thanks.

Here's a clip from my website with some pointers:
---------------
XXDP -- I downloaded this, but haven't used it yet. It is my
understanding that this is required to setup the RQDX3.
manual: http://www.conknet.com/~w_kranz/pdp11/xxdpdoc.txt
software:
ftp://sunsite.unc.edu/pub/academic/computer-science/history/pdp-
11/xxdp/
---------------
I'm probably going to face some of the same problems you are
facing. I'm still using the Andromeda UDC11 on my 11/53, which
works well, but I've got several RQDX3's I'll eventually have to
get working. I'm in the process of building several 11/53's from
scrounged parts.

There is an XXDP program to do this, as well as the MV II Diag Tape (not
the customer diag tape though). However, the easiest way to do it is with
a VAXstation/MicroVAX 2000 which has the necessary routines in it's ROMs.

While the original question was in regards to an 11/83, I wanted to jump
in on the VS/MV2000 recommendation and mention that I have found a couple
of disks that would _not_ format under the ROM formatter there, but would
do so on a uVAX-II w/FS Diag Tape formatter. The disks in question did
have bad blocks that needed to be mapped and there was some reason I never
did understand why the MV2000 could not do it. It appeared to work, but an
Ultrix 2.0 install failed at the same point every time, due to the bad block
that wasn't properly mapped out.
