PI/4D component compatibility

[Jeremy Nussbaum]

We have some 4D's and some PI, and want to move memory and disk drives
from the some of the 4D's to the PI's.  I realize that ESDI disks cannot
be controlled by SCSI controllers, but aside from that, what
cannot be taken from a 4D and put into a PI?  We were told that the
disk drives could not be transferred.  Is there any problem with the
SCSI disks on the 4D's being moved to PI's?  What about memory?

Thanks,
