The answer was to apply patch_fdc82077 to "support the Intel 82077 chip
as an alternate floppy disk controller chip", found in this case on the
SunOS 4.1.3 install CD. There was no strong opinion expressed over
whether or not 4.1.4 would include this. Exclusion of the patch
itself on the 4.1.4 cd suggests it has been wrapped in.

Of the four responses elicited, there was a suggestion that I
"check the obvious"-- that the cables were firmly seated, and
that the kernel had floppy support. He also recommended "upgrading
to SunOS 4.1.4 for another half dozen reasons", especially for its
 bug fixes for microSPARC architectures.

Another thought 4.1.4 would have the same problem, and pointed
out helpfully that "Standard Sun 1+ and other clones don't
need any patch for the floppy to work."

The third sent me a long list of places to get patches,
and suggested I grep for 'floppy' in the corresponding
README's to find the desired patch. This list is included below.

The final response was the patch itself from a 4.1.3(_U1 ?) cd.
