It's a shame that no one has yet built one of

to an MFM controller. That would have a much wider impact than SCSI.
That would be a handy product, but as discussions of same have pointed
out on this list, it's not as easy of a target (no pun intended)
because it involves analog sampling/synthesis at high (5MHz) rates and
a plethora of on-disk formats.
Not impossible, but nowhere near as easy as sampling an 8-bit bus with
handshaking and a defined command set. With classic hosts, the rate
tops out around 2M transactions/sec and is often quite a bit lower
than that (PIO SCSI interfaces for the Amiga, for example).
