Adding additional RAM cards<br />
In the event of an installed <strong>PC3000</strong> application being extended to provide additional<br />
control features it may be necessary to fit additional, or larger capacity, RAM cards.<br />
The metal sleeve should be removed as described previously.<br />
With the motherboard on a suitable anti-static surface remove the retainers by<br />
unscrewing the self-tapping screws. The RAM card may be replaced by unplugging<br />
and removing the card and plugging in the replacement, taking care to ensure that the<br />
sockets are aligned correctly and that the RAM card sits squarely on the motherboard.<br />
Refit daughterboard retainer and sleeve in the reverse order.<br />
Note: The second RAM board slot may only be fitted with the <strong>12</strong>8K<br />
byte RAM card.<br />
