Disks are just sectors. I think that's true generally; if SIMH supported any
systems with variable length disk blocks something else would be needed, but
the only system I can think of that does so is the IBM 360. (Actually, that
one is much stranger, with its keyed sector feature.)
Note that sector sizes may be 512, as for RK05, or something else. RC11 has 64
byte sectors, RF11 is word addressable. And IBM 1620 has 200 digit sectors if
I remember right.
