Apparently they have.  On an OSx4.4 system ...

	[sugar] ls -l /dev/iop/plp0
	c-w--w----  1 lp        48,   0 May  4  1988 /dev/iop/plp0

while on OSx5.0 ...

	[pyrps5] ls -l /dev/iop/plp0
	c-w--w----  1 lp        43,   0 Jan 11 11:55 /dev/iop/plp0


And as cal@pyrtech (Craig Alan Levin) noted in <98007@pyramid.pyramid.com>,
the major number can be verified by looking at the cdevsw[] table in
/usr/sys/conf/conf.c, which on OSx5.0 contains the entry

	/* 43 */ {	/* IOP printer */
		glpopen,	glpclose,	nodev,		glpwrite,
		nodev,		nodev,		nodev,		0,
		seltrue,	nodev,		SLAVEOK,	0,
		sio_nodev,
	},

So your /etc/makedev is correct and it looks like the man page for
plp(4) didn't get updated in the 5.0 release.  I'll pass this on to
the appropriate people.  Thanks for pointing it out.

Mike.
