3.2.57 Memory Expansion Board (DOC-IT Controller)
Note:
Two memory expansion boards (SIMM) are available for the DOC-IT controller board.
One board has one megabyte of RAM. The other has 2 megabyte of RAM. The boards
may be installed in either of the two available sockets. RAM is mapped correctly,
regardless of where the expansion boards are installed.
· Remove the DOC-IT controller board from the computer.
· Release the right locking tab.
· Release the left locking tab.
· Lift the memory board (1) until it is released from the tab.
· Rotate and remove the memory board.
Installation
· Position the expansion board so the key is facing to the left.
· Slide the board into the connector slot.
· Push the board until the locking tabs snap over the edges. You may have to push at the
edges of the expansion board to engage the tabs.
CAUTION:
When the amount of memory on the DOC-IT controller is upgraded, the CONFIG.EXE program
must be run for the DOC-IT. This will change the amount of memory detected by the DOC-IT
Manager. If the CONFIG.EXE program is not run, the expanded memory will not be detected.
Replacement
When replacing a DOC-IT controller board, move the original memory to the replacement board.
