	Okay -  here it is:
        My MacII (real mac II no suffix w/ PMMU chip) has 2 meg
currently and I have banks of 1 meg chips = 4 meg.  They are SOJ and
100 ns.  So I feel that (after backing up) I'm ready to replace one
of the banks resulting in 5 meg internal. Now here's the question...

	I have two different looking sets of memory in the two
banks.  In bank A it is taller and there are resistors on the boards
and in Bank B they are shorter and are NEC chips.  Can I put the 4
megs into either bank and if so which type of chips should I
replace?  I'm assuming the A-bank are the Apple-tm chips that came
in the machine and the smaller B-bank chips are dealer installed and
therefor I should go with the Apple chips -  but do I have to put
the 4 meg in Bank A necessitating shifting the Bank A 256s into bank
B and is that worth it?????

	I realize this is probably a tad confused but I think anyone
familar with the requirements this is nothing new.... anything I
should be aware of as I trek into the interior of my mac?  and will
I have to rebuild my desktop?  I don't see why I should have to but
I heard that somewhere????

	Anyway... Thanks in advance.... *8^}
