Newer simpler and more exciting:

Intel released the sequel to their popular i82072 FDC on a chip with
the i82077.  The 82077 has added features including the perpendicular
recording format of some unknown Toshiba drive (?) and built-in drivers
to make a neat one-chip solution.  I just finished marrying it to
an 80C186.  I needed to add a pullup sip resistor pack, three caps, a 
68pin PLCC socket, 20mhz crystal and a 34pin connector.  It does have
a neat data separation scheme which could be better than analog or digital.

I got one in my hands for $27 from my distributor.  I didn't want cheap,
I wanted something SIMPLE and easy to get working.

P.S.  Any information on the Toshiba recording format would be VERY
much appreciated!
