Actually, there is no need to change the system board (as we call it) unless
you want to upgrade the machine to a 1000-80. The XBI should be removed (it
no longer serves any purpose) and the operating system should be loaded from
tape (for this system board you need 3b2 UNIX release 3.2.1, 3.2.2, or 3.2.3)
via a full restore. The only difference between the system board in the ACPs
and a stock 3b2, is the firmware (if it is different at all). This is so
you can boot through the XBI board. It is backward compatible to the 3b2.
