2 GETTING STARTED
DIGITAL provides either an LA 120 DECwriter III, VT100, or VT102 terminal
for the PDP-11 /23-PLUS system (see Chapter 6). The system terminal im-
plements communication between the user and the processor. Interface
with the system and the user's terminal is provided by a patch and filter
panel located at the rear of the system's cabinet. Chapter 5 contains a
complete description of the PDP-11 /23-PLUS.
CONTROL PANEL
Control panel switches provide power, stop, and bootstrap commu-
nications between the user and the microcomputer system. This panel
contains three switches: AUX ON/OFF, HALT, and RESTART. Switch lo-
cations are shown in Figure 1-2, and their operation is listed in Table 1-1.

The switch panel contains three LED indicators, but only two are used:
POWER OK and RUN. Their operation is listed in Table 1-2.
SYSTEM CONFIGURATION
The PDP-11 /23-PLUS is configured and tested at the factory and is ready
to be installed at the user's site. Several features can be changed when
the system is installed by DIGITAL's Field Service. Figure 1-3 is a check-
list to use as a reminder of the desired configuration when the system is
installed.
RL02 Disk Drives
The RL02 disk drive is a random-access, mass storage device with a re-
movable, top-loading disk cartridge. A cover lifts up to gain access to the
disk. The RL02 has four indicators on its front panel, as shown in Figure
1-4. Their operation is listed in Table 1-3.
