The connector has 30 pins. It's a dark grey Apple SCSI cable (to
Centronics 50 female). That means it's a SCSI dock mode cable. Is
there any way to adapt the cable so that it will work as a standard
SCSI cable?

time I try to boot holding down the "C" key it comes up in SCSI disk

can't get it to boot off the CD-ROM.
The "2" means the laptop is coming up in SCSI Disk Mode. That means
the laptop is making the internal harddisk appear as a SCSI drive,
number 2. The intent is to allow you to plug the SCSI cable into a
Mac and do formatting / installations on the PBs hd via the other Mac.
Take a look at your SCSI cable, the part that plugs into the PB (or
via an adapter). There should be either 29 or 30 pins, the
difference is one pin in a corner. If the pin is missing you have a
standard SCSI cable. If the pin is there you a SCSI disk mode
cable, either full time or switch selectable. See if there is a
switch located somewhere on the cable. If the connector has the pin
(it should since your PB is going into SCSI Disk Mode) and has no
switch then you need to get another SCSI cable.
