Memory Capabilities
Figure 1-6 ROM, DRAM, and EPROM locations on the controller board
Table 1-5 lists the possible DRAM configurations for 4, 8, and 16 MB SIMMs installed in
the LaserWriter 16/600 PS printer.
Note
The larger SIMM must always be installed in the B A SIMM bank.
Otherwise, the printer will fail to come online and the Paper Jam and
Paper Out lights will flash indicating a printer error.
