INSTALLATION

Installation Procedure

To install a set of RAM chips lay MultiRam C down on a table with the socket side up. The eight sockets of Bank A will be at the top left end (see Figure 2.1); there should already be a set of 256K RAM installed in that bank.

Install the next set of RAM into Bank B on the bottom left of the card.

Most RAM chips have a notch or dot at one end to designate pin one. The chip's notch should match the notch on the chip drawing under the socket. The notch should face up toward the top of the card on both Bank A and Bank B.

WARNING! IF A RAM CHIP IS INSTALLED BACKWARDS, IT MAY BE DESTROYED WHEN POWER IS TURNED ON. THE MULTIRAM C CARD WILL NOT BE DAMAGED.

Carefully line up both rows of pins with the holes in a socket and press the chip into the socket. seating it firmly. Check that none of the pins are bent out or bent under the chip. Repeat the process with each chip until the bank is filled.

When you have finished installing any additional memory, you are ready to install the MultiRam C Card with the power TURNED OFF in your computer.

If you have any doubts about removing or installing the chips, have a service—person do it for you.

RAM Removal

If you incorrectly insert RAM into the card and need to remove it or if you are removing RAM from another device to insert into MultiRam, you should use an “IC—puller” (an inexpensive tool designed for removing integrated circuits. and widely available at electronics supply stores). Lacking an IC—puller, an ordinary flatware spoon can be inserted between the chip and the socket and the bowl portion can be used to rock each end of the chip lose. If a spoon will not fit, you say insert a flat blade between the RAM and the socket and pry up the RAM chip. Be very careful if you use a knife or other sharp flat blade.

Carefully remove each chip from its socket by gently prying the ends of the chip upward, a little at one end and then the other, being careful not to damage or bend the pins. Be sure you are prying only the chip and not the entire socket; very little pressure is necessary.

Dealer Installed RAM

You may have your dealer install RAM at the time you purchase your card or at a later date. Be certain that the installed RAM passes the test program supplied with the MultiRam C Card (described in Chapter 3).

Refer to Chapter 10 if your card containing dealer installed RAM is in need of service.

Factory Installed RAM

You may return your card to Checkmate Technology to have additional RAM installed. Ill factory RAM is thoroughly tested on the card at the factory and is warranted for five years. Refer to Chapter 10 for core information.
