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.
