1 Card Setup
Memory Banks
The PEI-306 RAM Card memory is divided into three banks. At the
very least, bank 0 must be full for the card to function. By setting DIP
switch SW1 and jumpers Wl - W3 the PEI-306 RAM Card can be set
up with a minimum of 1 MB and a maximum of 12MB memory.
The PEI-306 RAM Card has SIMM-type RAM module sockets. These
30-pin single-in-line sockets are aligned at an angle of 25 degrees.
Refer to the figure below.

Remember that when inserting the RAM module, you must make sure
the notched or dotted end of the module is lined up with the notched
end of the socket. Gently push the RAM module into the socket.
Three banks (bank 0, 1 and 2) for memory are on the PEI-306. Each
bank accommodates a 32-bit wide data bus. Bank 0 must be filled first.
