Expanding the MPC3k's memory:

Expanding the MPC3k's memory is fairly easy to do. Just remove the 10 or so screws aroudn the edge of the MPC and setting upright raise the top panel a few inches. Be careful not to pull any of the ribbon cables loose. The memory slots are located right in the front of the MPC. Remove the installed 8 or 2 Meg board that sticks sideways next to the memory slots (if there). Install the two 16 Megs chips in the two white slots. I've found the chip from this company for a very good price (about $50 for the pair). They are the 30 pin SIMM's:
