Jerome Fine replies: I know you said off-list, but I think that a public discussion of exactly what such a distribution kit should consist of is well worth while. I can probably help with any RT-11 distribution. As for a bootable RT-11 kit, I suggest that if anyone is using SIMH or E11, then the RT-11 binary distributions at: http://www.classiccmp.org/PDP-11/RT-11/dists/ RT11DV10.ISO.zip contains all RT-11 binary (many early ones incomplete) distributions up to V05.03 or RT-11 and is legal to use with SIMH. For a real DEC Qbus PDP-11, the RQDX3 controller and an RX50 floppy drive might be an alternative. RX50 bootable images can be produced on a PC using PUTR and a HD 5 1/4" floppy drive if you still have one, although the media MUST be the DSDD 5 1/4" media used with 360 KByte floppy drives, not the HD 1.2 MByte floppy drive - even though the HD floppy drive is actually used on the PC. When used in a BA23 box change from the 50 pin RQDX3 controller to the 34 pin connector.
