Guys,
I'm working on a special TU58 emulator called "tu58fs".
It saves the "tape content" not only in a binary image file, but also as a file
set in a shared directory on the host.
The content of the "tape" (as seen by the PDP) changes automatically as files
are moved in and out of the shared dir.
This works in both direction: creating/changing/deleting a file on the "tape"
modifies the files in the directory.
Neat!
tu58fs is intended to be a general tool for easy file
sharing between a PDP and the modern world. For this as much DEC filesystems as possible
should be implemented.
We need more than XXDP, but I wasn't able to find documents about the structure of
DOS-11, RT-11 or FILES-11/ODS-1.
Any links?
I've written (bad?) Python code to manipulate RT-11 filesystems, including on TU58
tape images:

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:
