> I don't know if Sun ever built a sun4c with a 82077 floppy chip,

The machine I'm playing with NetBSD/sparc on is a real Sun IPC...though
I admit I don't know whether Sun built it or OEMed it.  It does have
the Sun logo and a label saying "SPARCstation IPC" (with the cutsie
lightning-bolt A in SPARC) on the front.

And the -current fd driver (without the recent patches) says it's got
an 82077.  I haven't opened the box to see whether it's telling the
truth.

And certainly under SunOS, arch -k says it's a sun4c.
