[Simh] VMS 1.5 installable?

Well, obviously there are differences. The TE16 is a Massbus tape drive.
The TS11 is a Unibus thing. Totally different. Both in how they connect,
how the programming model is, the exact layout of registers, and of
course then, through which bus interface you program them.
In essence, they have nothing in common, apart from that they both use
the same physical tape medium in real life.
