INTRODUCTION
CHAPTER 1
GETTING STARTED
The PDP-11 /23-PLUS is a high performance microcomputer system used
for developing and executing programs for a variety of applications. Op-
tional hardware and software are available for applications such as high-
level language program development, foreground/background real-time
support, multiprogramming, and equipment monitoring and control.
The PDP-11 /23-PLUS (Figure 1-1) includes an operator's switch panel, a
processor with memory management functions, a 256K byte memory (ex-
pandable to 1 megabyte), a 2-channel serial line interface, and two RL02
disk drives. The memory supports the extended LSI-11 bus (22-bit ad-
dress). Each disk drive has a removable top-loading disk cartridge that
provides 10 million bytes of storage. Special bootstrap read-only memo-
ries (ROM) initiate the system software when the system is turned on and
can also automatically test the system.
