Macintosh LC: Expansion Board Not Necessary for RAM Upgrade


My Macintosh LC Owner's Manual says that the Macintosh LC comes with 2MB
of RAM on the motherboard that can be upgraded by adding another board AND
THEN adding SIMMs to this additional board.

It certainly looks like I can put two or more 1MB SIMMs right onto what
looks like two SIMM slots on the system board. To the left of these slots
is a big chip. Is that the 2MB of RAM is this a ROM chip? If it's a ROM
chip, are those four little chips to the left of that the RAM?

The Macintosh LC doesn't need a memory expansion card. If the manual
states that, it is incorrect. Simply adding two SIMMs will upgrade the
memory.

Macintosh LC RAM is on four chips on the other side of the ROM SIMM
socket. These RAM chips are labeled "DRAM".

To see the possible memory chips and configurations for the LC, search
under "DRAM Specifications".
