The PB520 and PB540 have a flawed early-revision 68LC040 processor* which
makes it unlikely that these machines are running Linux (or NetBSD). A few
have had backyard CPU upgrades, like my own. I'll test MAC_SCSI_OLD at
some point, but I don't know when that will be.

The PB550 doesn't have the 68LC040 problem but it was only available in
Japan. These machines may have Linux or NetBSD on them, but they are rare
and their owners may not be found on these lists.
