I would like to do a bad sector scan on a RD52 connected to a RQDX1 controller (The machine is a pdp11/73 without OS) prior to installing BSD2.11.Is there a standalone program like zrqch0(standalone version of zrqc from the xxdp package - only for RQDX3) that can be downloaded directly to the pdp via vtserver and recognizes the RQDX1 , i.e. a version of zrqb or something similar?
