 Did anybody ever use a serial chip and a data
separater
rather than a floppy disk controler? 
Yes, many.  usually its a sync chip.

Hi
 Besides the HeathKit hard sectored controller board,
used on both the H8 and the H89, Polymorphics also
used a serial chip to do data. In both of these
cases, as you state, they used synchronous serial
chips and not async.
