Does anyone know what the switch register settings are for the PDP-8 disk diagnostics (found on diagpack2.rk05 and others)? In particular, the AJRL** series (RL01/02 drive exercisers). Normally the SR is set to 0000 but when there's an error the program stops until a CR is typed. I want the diagnostic to just print out that error and keep running. Trial and error might take a long time. Without the source code there's no other good way except possibly to single-step through the program and look for the OSR command (which may also take a very long time). thanks for any help. -Charles
