Instead we should aim at getting a "1970s version

Later things can be expanded to talk IDE/SCSI whatever - but at that
point you are evolving the "1970s version of Unix" on a stage further -
Screen => console tty is obvious. But why do you insist on the floppy
drive as the storage medium?
The floppy drive subsystem has drives and a controller with a certain
programatic interface. The IDE/SCSI subsystem has drives and a controller
with a certain programatic interface. They're the same kind of thing.
Why is one more guilty of evolving the 1970s version of UNXI?
I think that a floppy might make a good RK03/05 (capacity differences
aside), but why not implement some RP drives with hard drives of even zip
drives?
