Anyone know the "secret" to opening up a 3B1?  After removing all the
screws everywhere (even the two hidden ones under the posts that secure
the keyboard when it's placed on the system unit), the front edge still
seems to be attached to "something."

Also, the parts and documentation lists that accompany the system
strongly suggest a 68881 can be plugged into the system.  See the UNIX
PC Service and Parts Ordering Information pamplet that was in the pouch
of the Owner's Manual (for 3.51), first page of the Parts List, item:

     COMCODE          DESCRIPTION

     105160253        Math Acc. Unit MC68881

also, on the LAST page of that pamphlet:

     405176785        Expansion Unit
      405198854       Ethernet Board


WHAT is the ``Expansion Unit''?  Something that will permit more than
three plugin cards?

Anyone know if there's a SCSI adapter card for the 3B1 too?

Thanks in advance!
