  My copy of the 1990 Peripherals handbook has the 82064 in it and yes indeed,
it does appear that there is another source of hard disk controller chips
available.  I checked the pinout of the 82064 against the WD1010 and all the
signals appear to be the same.  I didn't check timing diagrams.

  Does anyone happen to have one of these lying around?  It sure would
be nice to know if they do work.
