I've written (bad?) Python code to manipulate RT-11 filesystems, including on TU58 tape images: https://github.com/NF6X/pyRT11 I don't remember which specific documentation I referred to when I wrote this code, but it may well have been something like this manual: http://bitsavers.trailing-edge.com/pdf/dec/pdp11/rt11/v5.6_Aug91/AA-PD6PA-TC_RT-11_Volume_and_File_Formats_Manual_Aug91.pdf -- Mark J.
