OK, done.

DU.COR                 patch for DU.MAC to use RQDX3 under RT-11 V5.01
DUX.TXT                explanation of above
DistrOVL.ps            component overlay for my RQDX distribution board
DistrPCB.ps            PCB layout artwork for above
M9058_layout.ps        component overlay for M9058 distr.board in BA123
M9058_schematic.ps     schematic diagram for M9058
RQDXn_LEDs_switches.ps schematic of the WR.PROT + READY switches/LEDs
RQDXn_pinout.ps        list of pins and signal descriptions for RQDXn
RX50_substitute.ps     notes on using floppy drives other than RX50

The first two are flat-ASCII; all the files with ".ps" extensions are
PostScript.  If you don't have a PostScript viewer (eg Ghostscript or
one of the Corel packages), you can send them straight to a PostScript
printer.

The ROM images for RQDX1, RQDX2, and RQDX3 are in

    http://www.dunnington.u-net.com/public/DECROMs/

See the file "00ReadMe" for information, "ROMlist" for a table of
part-numbers/module-numbers/versions, and "Wanted!" for, well, "wanted"
:-)
