Thanks a lot for the manuals and schematics. Will be really helpful when I get to work with RC11/RS64. You don't happen to have the diagnostic listings as well? I found a ZRCAB0 and ZRCBB0 diagnostic but not any matching listing. Haven't found a ZRCC diag as well. So, if you have diagnostics listings and matching binaries or just listings that would be very interesting as well. > > Note the drawing updates for the RS64 to take it from revision H to > revision K (and perhaps L - but that part was written over in ink on the > copy). > > Also, note that manual > > DEC-00-HRS64-E-D_RS64_disk_file_maintenance_manual > > Has a page that was placed in the document by Professor Marleau of UW > (Wisconsin) Electrical Engineering.
