eventually found a description of the DC003, 004, 005,
006 & 010 in "The
Chipkit Users Guide" on the QBUS IDE project page at
http://www.chd.dyndns.org/qbus_ide/
Hit SEND a tad early on that other one!
Various DEC manuals describe various
DEC chips in their appendices. The DHV11
tech manual happens to cover all of the
above except the DC006. One copy lives
at
http://www.spies.com/~aek/pdf/dec/qbus/
I have not read that chipkit manual, but the
DHV11 manual includes a schematic so you
get a free reference design.
