Table 2.1
If your card only has 64K of RAM installed, you may wish to add RAM to it
at a future date to increase its memory. RAM may be installed by you, the
dealer, or Checkmate Technology. See the User Installed RAM section of this
chapter for details.
Original Ram
Each MultiRam RGB card is shipped with a minimum of 64K in RAM Group
A, which means RAM Group A will have a full set of eight RAM chips.
RAM Group A must be populated with at least 64K chips in order to provide
80-column video and to work with those programs requiring a 128K Apple //e
configuration. Your MultiRam RGB card may contain RAM in other banks
or 256K RAM in RAM Group A as your dealer may have ordered the card
with more memory or may have installed his own RAM chips.
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 (//e card’s
warranty. Checkmate Technology guarantees for seven years only those RAM
chips that are installed and tested at the factory or RAM chips sold in kits by
Checkmate Technology, Inc.
We cannot guarantee non-Checkmate Technology RAM chips which are added
by you or a dealer. Refer to Chapter 7, which explains the terms of
Checkmate Technology’s seven-year warranty on the card and its components.
