Appendix
Installing Memory Expansion
The MPC2000’s internal memory can be expanded to 32Mbytes using
SIMMs. The MPC2000 comes with 2Meg of memory ‘hardwired’ and
there are two slots in which you can install SIMMs chips. The SIMMs
board is inserted at a slight angle and then pushed back where it clips
into place. Because SIMMs boards can differ, it is not possible for us
to say “Install them with the components facing the front of the
MPC2000” or anything like that because some SIMMs boards have
the memory chips mounted on both sides sometimes. However, the
boards can only be inserted one way so you shouldn’t have any prob-
lems but be careful not to force them into place otherwise they may
snap.
SIMMs operate a different speeds. SIMMs that operate at at a speed
of 70nS (nanoseconds) are recommended.
SIMMs also come in various sizes. Please note the following memory
configurations that are possible in the MPC2000.

Note: Memory chips are sensitive to static electricity. Please ob-
serve the following safety precautions:
• Unplug the MPC2000 before installing the board(s).
• The SIMMs may come with a special wrist strap to dis-
charge static electricity. We suggest you attach the strap
to the MPC2000’s case. If a wrist strap or any other such
accessory is not supplied, try discharging any static by
touching an earthed metal object before handling the
boards.
• Always handle the memory board by its edges - avoid
touching the components on the board.
• To minimise static electricity, avoid carpeted areas and
low humidity areas.
