does anyone know of an on-line manual for the RQDX3 disk controller? The printset is here: http://bitsavers.org/pdf/dec/qbus/MP02259_RQDX3_schem_Oct85.pdf I have a scan of EK-RQDX3-UG-001 "RQDX3 Controller Module User's Guide" which does not appear online. Email me if you want it, and I'll see that it gets put up somewhere soon. Antonio arcarlini at iee.org
