Memory Upgrades - Mitsubishi Electric Apricot LS Pro Using Setup And Installing Add-Ons

Memory upgrades

Memory on the Apricot LS Pro can be expanded to a
maximum of 16 Mbytes by fitting SIMMs (Single In-line
Memory Modules) in sockets provided on the system
board.
The SIMM sockets are grouped in pairs, which correspond
to blocks of memory known as banks. Four banks (banks 0
to 3) are supported.
During manufacture 2 or 4 Mbytes of RAM is soldered to
the system board. When 2 Mbytes of RAM is installed only
bank 0 is occupied and six SIMM sockets are fitted. When
4 Mbytes of RAM is installed banks 0 and 1 are occupied,
and four SIMM sockets are fitted.
Apricot memory upgrades are supplied as pairs of SIMMs,
with upgrades of 2 and 8 Mbytes available. The illustration
below identifies the SIMM sockets and banks:

Note
When 4 Mbytes of RAM is soldered to the system board
during manufacture the SIMM sockets for bank 1 are not
fitted.
