Please don't say "unnecessary" ... my home machine (a clone

the patched fd.o that comes in the patches area on the SunOS 4.1.3
CD-ROMs)
My impression was that the 82072 and 82077 are basically the same,
except that the 82077 does perpendicular recording, and requires more
anality in initializing it.
It should be easy to make a driver work with both.
=> I have just opened an ELC and a SS1+. The ELC has no FDC, the SS1+
has an Intel 82072, then I believe we need a driver for both 82072 and 82077.
I have done a very minimal driver implementing only the floppy useful
function eject (it is a joke, not a floppy bashing). It should work
on any host and it avoids the horrible "not configured" message at boot time.
I'd like to write a real driver but I've got only the Intel 8272A doc
(it is the same kind of chip but it is a bit old)...
