64K-256K System Board Switches
To use the following switch setting charts, your system
should have a "B" stamped on the rear panel, and the
system board should have 64KB-256KB CPU printed
on the side.
The switches on the system board are set as shown in
the figure below and on the following pages. These
settings are necessary for the system to address the
attached devices and to specify the amount of memory
on the system board.
Two types of DIP switches are installed on the system
boards and option adapters. Set a rocker switch by
pressing down the rocker to the desired position. Push
a slider switch to the desired position.
Warning: Before you change any switch settings,
make a note of how the switches are presently set.
