[4 drives/controller]
OK... All the single-chip floppy controllers (that's FDC + clock + data
separator + PC-style drive logic on one chip) that I have data sheets on
only support 2 drives
There are probably some custom chips that support all 4 drives, but then
I don't use chips I can't get a full data sheet on in any machine that I
depend on...
Equally likely, there are chips that I've not come across yet...
Well, the CompatiCard IV uses the NEC N82077-1, the WD FOX has a
WD37C65BJM, and the DTK has a NS DP8473V.

Unfortunately all the single-chip floppy controllers only support 2
drives. Great pity...
Not true, Tony, if you are talking FDC chips. The CompatiCard IV is a
single chip, as are the WD FOX and some DTK cards and others as well.
