Is there any reason not to just track down some WD92C32 or WD92C16? 
I think SMSC (FDC prefix) sold some similar chips too.

The only problem is, I've been looking for WD92C32s for a few years 
and there seem to be plenty of them in the hands of the folks who 
*always* come up on Google searches of electronic part numbers and 
they all seem to want >$3.50 each and a hundred dollar minimum or 
more.  Sigh.   When you're trying to build something that might be 
worth $15, it's hard to spend $3.50 on one component.

I did see a nice lot of WD92C16s on Ebay a year or two ago.  I think 
that will work as long as you need to read 1.44MB floppies.  But I 
haven't seen any more of them since then.
