Try skipping forwarding one or two file marks.? There was some kind of
stuff at the beginning of the tape that I didn't recognize.? The monitor
was after two file marks.? So do a rewind then skip forward one file
mark and maybe mtboot will be there.

In the end (!) the tape recipe works as follows:
Get a FRESH ?copy of tape BB-D867E-BM_TOPS20_V41_2020_INSTL.TAP-1
(after unzip) from Pdp10 archive into a host directory.
In simh when the monitor Tops20 V4.1 has been fired up or before:
ATT ?F TU0 SIMH G:\TEMP\BB-D867E-BM_TOPS20_V41_2020_INSTL.TAP-1 or
your favorite location
I found that SIMH is happy attaching it with -f tpc -- previously I
had misread the messages printed by that command and thought it had an
error.
So according to the installation manual, that tape is the "install"
tape and is supposed to be bootable. ?But if I mount it and issue
"boot tu0", nothing happens. ?When I stop simh it tells me PC is 0.
