1.	Turn off the mac and let it sit for a spell.

2.	Remove all four case screws [two down by the mouse/disk/serial ports,
	two inside the handle; you will need a long-shafted Torx T-15 driver]

3.	After pulling the back off the Mac, take a look at the top of the
	motherboard and find the big molex-type connector that feeds power
	to the motherboard.  Disconnect this connector. Disconnect the HD
	cable and floppy cable at this time as well.

4.	The motherboard sort of slides out a little bit then tilts out towards
	the bottom.  It's a lot harder to explain than it is to see.  Take a 
	look at the notches along one edge of the motherboard and the matching
	notches on the metal frame ond you'll figure it out.

5.	Now, you will see eight SIMM sockets near the front of the board. The
	SIMMs are latched in at either end. Examine these latches and after
	you've figured out how they work, use a penknife blade or something
	similar to release the SIMMs.

6.	Move the four SIMMs that are presently in place into the four slots 
	that are presently empty.

7.	Put your four new SIMMs into the newly-empty sockets.

8.	Now start at Step 4 and work backwards to put everything back together.

Cautions:

When opening the back of the Mac, be advised that the picture tube holds a 
charge of sufficient voltage to injure or kill you.  Stay away from it.
If you have the appropriate tools, that charge can be dissipated, but I've
upgraded several machines without doing so; I take my time and stay away from
the tube.  Unplugging the Mac several hours before you begin this procedure is
a fine idea, as well.

Take care not to force anything.  Once you figure out how the various sockets
and connectors fit together, everything comes apart fairly easily.  The molex
connector on the motherboard is an exception. It always seems tough to undo.

When removing the SIMMs, take care not to scratch or chip the motherboard if
you're using a penknife or something.  If you have stronger nails than mine,
you may be able to use them instead.

That should be it.  With the SE/30 and above, there is no need to clip 
resistors or move jumpers to effect the memory change, as there is on Plus or
SE machines.
