There is no reason you can't have two simulated controllers, one small enough and
early enough to boot a range of operating systems (RL02?), then
another which exports a simple block-level interface which would be simple enough to
easily write drivers against.
RL02 is also interesting because there was a 22 bit version for qbus.
I'm trying to remember if DSD had extended block length or partioning for their
controllers.
