You could totally do this yourself. You will have to buy 256MB pc133 144pin SODIMM SDRAM. look for my explanation at the link below.

Like I said, you can do this yourself. Make sure the unit is turned off and unplugged. Turn the MPC upside down, you will see a little square panel that has 1 screw on it. unscrew it and lift off the panel, you will see a slot. The memory chip can fit only one way. Once you place the chip in, push down until it clicks. screw the panel back in place, flip it over plug it up and turn it on. you will know it's done correctly when you see "128MB installed" on the screen as it comes back up.
