There are two major voids in NetBSD/pmax.  Missing audio driver of
IOASIC DECstation built in and no floppy driver for MAXINE.

Both projects are not hard to accomplish.  Take a look at NetBSD/sparc
port and run analysis and research on how existing codes are applied.
Specifically, in 'arch/sparc/dev' directory;

	am7930_sparc.c
	fd.c, fdreg.h, fdvar.h

Jonathan Stone once tried to modify the original 7930 codes in some
degree.
