DRAM Expansion 1
You may expand the LaserWriter Pro printer’s DRAM capacity using SIMM (single
in-line memory module) cards, which are plugged in to the slots on the surface of the
printer’s main circuit board. As shown in Figure 1-9, there are two slots for SIMM cards.
Slot 1 is the slot closer to the edge of the circuit board.
Note
There is no silk-screened identification of these slots.
To expand DRAM capacity, you must use one of the configurations listed in Table 1-10.
