INSTALLING MEMORY EXPANSION
The CD3000XL’s internal memory can be expanded to 32Mbytes giving a massive recording
time of nearly six minutes. The CD3000XL comes with 8Meg of memory ‘hardwired’ and there
are two slots in which you can install SIMMs chips. Installation is fairly simple. 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 to say “Install them with the components facing the front of
the CD3000XL” 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 problems but be careful not to force them into place otherwise they may
snap.
SIMMs operate at different speeds. SIMMs that operate at 70nS (nanoseconds) are
recommended.
SIMMs also come in various sizes. Please note the following memory configurations that are
possible in the CD3000XL.

NOTE: Memory chips are sensitive to static electricity. Please observe the following safety

precautions:

Unplug the CD3000XL before installing the board(s).

The SIMMs may come with a special wrist strap to discharge static electricity. We suggest

you attach the strap to the CD3000XL’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.
