Adding more memory
The computer has 4 megabytes (Mbytes or Mb) of random-access
memory (RAM) fitted directly onto the motherboard. You can
add more memory up to a maximum of 64 Mbytes by the use of
one or two standard SIMMs (single in-line memory modules).
There are two SIMM sockets on the motherboard, labelled
MM1 and MM2. Each socket can be left empty or fitted with a
SIMM. SIMMs with capacities of 4, 8, 16 and 32 Mb are
supported. When a 32␣ Mb SIMM is fitted in the MM2 socket,
the 4␣ Mb motherboard memory is automatically disabled.
The following table shows the recommended configurations.

In most cases, it does not matter which SIMM goes in which
socket, but some configurations are less efficient than others. If
the BIOS detects an inefficient configuration it will prompt you
to swap the SIMMs over when you next turn on the computer.
