     This might help:  I received two MacIIx's at the same time.  One had 4
SIMMs in bank B (as I've just learned) and its HD data and HD power cables
could handle 2 hard drives.  The other IIx had cables for one drive and no
SIMMs.  Both give a chime.  Neither has HD or floppy and supposedly neither
would come with RAM, although one of them seemed to.  :)  They essencially
seem to be logic boards in cases with power supplies and some cables that
don't lead anywhere.  I have one MacII video card that I've been putting in
these Macs.  Oh, and they both have what appears to be a ROM.  When I take
it out, they don't even chime.

     Any ideas?
