Needed: Diagnostic listings for DEC RL controller&disk drives

Hi all, I'm trying to repair a bunch of DEC RL11 controllers. (These are the UNIBUS boards for RL01/RL02 disc drives). Running the PDP-11 diagnostics ZRLA, ZRLB, ... ZRLN from XXDP or papertape prints out some errors, but without the diagnostic assembler listings I don't understand what's wrong. At the moment I know only of these 4 listings: AC-E040B-MC_CZRLBB0-RL11_RLV11-Controller-part-2_Oct78.pdf AC-E044B-MC_CZRLCB0-RL01-Drive-Test-part-1_Oct78.pdf AC-E048B-MC_CZRLDB0-RL01-Drive-Test-part-2_Oct78.pdf AC-E246B-MC_CZRLEB0-RL01_RLV11_Exerciser_Oct78.pdf These are all for paper tape based MAINDEC diagnostics, and are also incomplete: At least both "part 1" AND "part 2" is needed for ZRLB, ZRLC, ZRLD. Can you point me to some hidden archives? Or do you have more assembler listings for ZRL diagnostics lying around? Bitsavers needs your input! Thanks, joerg
