Speaking of the 765s, I still need to build an MFM data
separator...
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.
