Upgrading The Motherboard; Adding More Memory - Mitsubishi Electric apricot ls/vs550 Owner's Handbook Manual

Upgrading the motherboard

Adding more memory

Fitting and removing DIMMs
Caution Caution
Care must be taken in the purchase of upgrade parts to ensure both
compatibility with the system and the compliance with appropriate
approvals and certification, e.g., CE marking within Europe. Using
non-approved parts may invalidate your warranty and system approvals.
The only tool required to complete the installation of the upgrades
is a small cross-head screwdriver.
Read all the instructions through carefully before starting. The tasks
are not difficult, but if you do not feel confident about the work
involved, you may wish to have your supplier or service organisation
complete it for you.
Warning Warning
Never carry out any work inside the computer with AC power applied.
Turn off the computer and unplug all power cords before starting work.
Memory can be fitted in three vertical DIMM sockets which must
be populated with gold contact, 3.3V, 72-bit unbuffered EDO type
DIMMs having 60 ns timing.
The three DIMM slots accept DIMMs of 16, 32 and 64 Mbytes
in any combination, to the maximum of 192 Mbytes.
Note the indents along the connector edge, they prevent the
DIMM from fitting into the socket the wrong way round.
