You are exactly right!

It displays V4.00.

I must take a look to my old SIMH installation since I wrote the
tapes from which I've installed the disk from there..
IMHO I've donloaded it with exactly that resorc.sav.

I'll try to find another one .. and a way to get it onto the disk finally.
As far as I remember I had an SIMH installation on my previous PC
and wrote tape files there that I copied to real tapes from which I finally
installed that RT11. (I have the disk contents of the previous PC archived
on tapes)

Thanks Jerome!
