Most of us don’t do it as a living but have piles of floppies that we want to recover
cheaply using an existing method. Grease, cat and other wezels, are fine but you have to
do more work to get usable stuff, unless your floppies are all c64 😀 The applesauce just
seems further along than the others.
Just my opinion.
To be fair, the OP was talking about replacing the WD disk controller.
As far as I know, WD 17xx and 27xx controllers can do FM and MFM. Heck,
they can't even do M2FM.
A small exception. Back in the 1970s, we did do GCR using the WD1781,
which is basically a 1771 without the modulation appendages. And even
then, it took a Multibus-sized board to implement the scheme.
