Checkmate Technology MultiRam C The memory card - Manual (Page 12)

2.2 INSTALLATION
Never insert your card into or remove it tram the computer while the Apple’s
power is on. You may damage the card, the Apple, and other devices attached to
the Apple. You will void your MultiRam
C warranty.
When installing added RAM, as discussed later, try to minimize the number of
times RAM is inserted into and removed from the MultiRam C’s sockets. Even our
quality sockets will be degraded by excessive insertion and removal of
RAM
chips.

After unpacking the MultiRam C card, carefully set it down on a clean, dry
surface, with the sockets and other component facing up. Do not remove the
anti—static foam protecting the connector pins at the bottom of the card.
Compare your card with Figure 2.1 and locale the following components.

There are two banks of sockets on the card into which RAM chips can be
inserted:
Bank A and Bank B.
Bark A is located across the top left half of the card. Bank A consists of
eight sockets, labeled A8 to Al from left to right, and its sockets are marked
by a line around them.
Bank B is located across the bottom left half of the card. Bank B consists of
eight sockets, labeled B8 to B1 from left to right, and its sockets are marked
by a line around them.
Adding to or changing the RAM chips of these two banks is discussed later.

Near the middle of the card are two empty sockets.
The top socket is the MMU socket and is labeled “MMU”. To install MULTIRAM C,
you must remove the MMU from the //c motherboard and insert the MMU chip into
MultiRam C’s MMU socket. The notch on the MMU must point to the left toward the
card’s RAM.
The bottom socket is the CPU socket and is labeled “CPU”. To install ‘MultiRam
C, you must remove the 65C02 CPU from the
//c motherboard and insert the 65C02
into toe MultiRam C’s CPU socket. The notch on the 65C02 must point to the left
toward the card’s RAM.
