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.
