Installation manual

Installation
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. A small flat blade
screwdriver may be used for the same purpose.
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. He sure you are prying only the chip and not the entire
socket; very little pressure is necessary. When the chip has been removed,
inspect it for bent pins. If a bent pin is found, carefully straighten it. These
pins break easily. A broken pin means the RAM chip is no good, and a bent
pin makes it very difficult to install the RAM chip. Take your time when
removing RAM chips to avoid this conflict.
Installation Order
If you are installing one or more banks of 256K RAM, we recommend you
follow the placement order shown in Table 2.1: first install a set of 256K
RAM in RAM Group A, second in RAM Group B, third in RAM Group C,
last in RAM Bank D. All 64K RAM should be installed to the right of or under
256K banks. In other words, install RAM clockwise, use sets of 256K RAM
before 64K and do not leave groups of sockets empty between filled groups.
Although the only essential RAM placement requirement for existing software
is that RAM Group A must always be populated with either 64K or 256K
chips for 80-column displays and programs requiring 128K to work, the
placement of RAM suggested in the preceding paragraph should insure that
future software developed for the MultiRam RGB by third party software
developers will work with the card. All software developed by Checkmate
Technology does not and will not require 256K RAM to be placed in any
specific location.
Installation Procedure
To install a set of RAM chips, lay the MultiRam RGB down flat on a table,
with the socket side up arid the bottom (with the row of gold fingers) towards
you. The eight sockets of RAM Group A will be at the top middle of the card
(see Figure 2.1); there should already be a set of RAM installed in that group.
If RAM Group B is empty, the next set of RAM should be plugged into those
sockets. If two sets are already installed, you may plug your RAM into Group
C. If RAM Group A contains 64K RAM, and you are adding 256K chips, you
should remove the chips from RAM Group A and substitute the 256K chips.
