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.
