Though not a disk controller, the DEC DR11-B/DA11-B
would not cross 64K
boundaries.
Interesting! What's odd is that the DR11-B uses the Bus Interface card (M7219)
from the RC11 controller, and that _can_ cross moby
boundaries, so clearly it
has the right overflow output; someone just decided not to
implement it - the
DR11-B sets ERROR instead on an address overflow. Wierd.
Anyway, it will be interesting to see if RSTS operates correctly once this
problem is fixed...
