Sharp MZ-800 - 7.2.3 RAM file board (MZ-1 R18)

7.2.3 RAM file board (MZ-1R18)
The RAM file board is a memory device which can be used in the same manner as floppy disk drives,
except that the contents of memory are lost when the power is turned off. For full details about the
RAM file board, see the manual supplied with the RAM file board.
The installation procedure for the RAM file board is as follows.
(1) Remove the three screws which retain the expansion slot cabinet as shown below. Push the expan-
sion slot cabinet toward the rear of the MZ-800, then lift the rear side of the slot cabinet to remove
it. Unplug the connector which is connected to the main unit by opening the connector latches.
