I'm talking about the DEC Q-BUS DSA world where there never was any ATA :-)

Doesn't ATA transfer the data in parallel??
ESDI uses the same two
connectors as MFM (20/36 IIRC) , and transfers the data serially.? The
difference between MFM and ESDI is that MFM transfers the raw analogue
data over the cable but ESDI transfers digital serial data.
I was speaking about the interface to the controller. Of course, if you
don't have the right controller, all bets are off.
