I may be a bit spoiled by (Net)BSD, which prints a nice device tree when
it boots: you can see which devices are attached to which buses, giving
their exact names. When simh shows "TU      Massbus adapter 1,
FORMATTER, TM03, 8 units" it doesn't tell me that said massbus adaptor
is called "RHB" (although that is mentioned in the help text for RHB).
It also doesn't help that DEC has these interesting tendencies to have
rather different names for the devices, controllers and their drivers
(and each of those is used, in various places). Of course, there is some
system to it, I see that, but it takes some getting used to...

(Note: I've been dabbling with VM/370 on Hercules, the IBM 3[679]0/etc
emulator, and that is waaaay worse... so everything is relative.)

I'm trying :)

Thanks for the exposition about the tapes. I have simply been trying a
few different configurations I found here and there until I got
something where I could (sort of) see why it worked.
