Original Ram
Each MultiRam C Card
is shipped with a minimum of 256K in Bank A, which means
Bank A should have a full set of eight 256K RAM chips. Your MultiRam C Card may
contain RAM in other banks as your dealer may have ordered the card with more
memory or say have installed his own RAM chips.
Look on the lower right hand area of the rear of your card to see what RAM was
shipped with the card. You should see a a "1" (shipped with 256K) or a "2”
(shipped with 512K) stamped in this area.
If the card, as purchased, is not configured as indicated by the code.
additional RAM has been added or replaced on the card.
It is normal for dealers to install their own RAM in order to limit the
different RAM sizes they stock. Dealer installed RAM does not void the card’s
warranty. We cannot, however, guarantee non—Checkmate Technology RAM chips
which are added by you or a dealer.
Checkmate Technology guarantees for five years only those RAM chips that are
installed and tested at the factory or RAM chips mold in kits by Checkmate
Technology, Inc., kits available at your local dealer. Refer to Chapter 9,
which explains the terms of Checkmate Technology’s five—year warranty on the
card and its components.
User Installed Ram
To install your own RAM, you will need to purchase one or more sets of eight
256K or 64K dynamic RAM chips. RAM on MultiRam C most always be installed in
sets of eight in order to generate 256K or 64K of memory.
Chips installed in a bank of sockets must always be all the same type —— 256K or
64K. Although mixing chips will not harm the RAM or the card, you will loan the
use of 192K of a bank of 256K chips if one 64K chip is accidentally installed
into the hank. Similarly, only 64K of a 256K chip installed into a bank of 64K
chips is usable.
Ask for a speed rating of 150 nanoseconds on the dynamic RAM you purchase,
although 200 nanosecond 256K or 64K DRAM chips will work in the computer. You
should try to purchase a set of eight RAMS that are the same speed and made by
the same manufacturer to minimize potential compatibility problems.
If you are unfamiliar with purchasing RAM, ask your dealer for Checkmate
Technology’s RAM Kit. The RAM in each (it is guaranteed to work with MultiRam C
when correctly installed, and are warranted for five years by Checkmate
Technology. If you return a card to Checkmate Technology with defective RAM you
inserted into the card (other than from a Checkmate Technology RAM kit), you
will be charged a service fee plus RAM replacement cost to repair the card.
