The SD controller is a large state machine.

You would need to 'upgrade' the PLDs with a small FPGA - but I would
think that it would be very easy to re-target this to a real Omnibus
implementation. The hard part is done.

Hi folks,
One that most users would want is a emulation of some mass storage
device like DECtape or RX02, or maybe RK05 (or 5F). This is the
most often needed item, second only to memory but that can be built
as semiconductor. The storage is a disk emulation, then can be
USB but IDE is easier to program on a machine with limited space.
Of the IO for storage SD, and CF are the two best shots as they have
the simplest and lowest protocol needs.
