One detail on "it doesn't care what the tape is": RSTS kits on 1/2 inch tape
come in 800 and 1600 bpi versions. They have different boot blocks, each of them designed
to work with all tape drives/controllers supported on RSTS that support the density in
question. For example, the 1600 bpi kit doesn't boot on a TM11 controller, and the
800 bpi kit won't boot on a TMSCP controller. This matters if you try to boot one in
an emulator where physical tape density doens't have any meaning.

I think all (modern PDP-11) OSes can install from
TMSCP tapes. RSTS/E is
more picky than some others, though, if I remember right...
Yes, RSTS/E installs from TMSCP just fine (as can RSX-11/M+); I know
that in simh you can bring up Ultrix-11 3.1 only on TMSCP
(specifically a TK50), at least if you want all of the packages to
install. I've installed RSTS/E 10.1-L from MASSBUS, TS11, TM11, and
TMSCP in my various experimentation with emulation, it really doesn't
care what the tape is as long as your SYSGEN device is consistent.
