It's a motherboard swap.  The crystal is clocked faster, plus the cpu chip is
faster and the floating point chip becomes a 68882 instead of a 68881.  These
are not user-replaceable parts.

You can add almost anybody's 3.5" SCSI drive in one of the 2 additional drive
bays in the A3000 case.  5 1/4" drives can go into an expansion case. There is
an external SCSI port on the A3000.

You'll find Kickstart images on the hard drive; one with 2.0x (probably 2.02 or
2.03) and another with 1.3.  You can select from either of these via a boot
menu.  The default out of the box is to load the Kickstart image from the
devs directory of the WB_2.x: partition.  2.0 ROMS are not available yet.
