At the very first moment after power on, the machine should show the
digital-notion of cryptic "model name" like "KN01" or "KN02-CA".  It
might help you.  According to pmax mail-list archive following models
are known to us.

KN01            DS3100          PMIN            2100
KN01            DS3100          PMAX            3100
KN02-AA         DS5000          3MAX            5000/200
KN02-BA         DS5000_100      3MIN            5000/1xx - xx = 20, 25, 33
KN03-AA         DS5000_300      3MAX+           5000/240 & 5900 & 5900/40
KN230           DS5100          MIPSMATE        5100
KN220-A         DS5500          MIPSFAIR-2      5500
KN02-CA         DSMAXINE        MAXine          5000/xx - xx = 20, 25, 33
KN04            R4_5000_100     R4000 3MIN      5000/150
KN05            R4_5000_300     R4000 3MAX+     5000/260 & 5900/60

RZ23L is 120MB SCSI. It's a slow drive, it would be better to throw it
