Workstations
The Central Processing Unit (CPU) of the computer controls all
other components of the system. It holds the operating system of
the HP250, which is software associated with the computer and its
processing capabilities. It also has at least 32K bytes of
memory available to you for programs and data; user memory,
capable of processing six tasks simultaneously, may be expanded
to 384K bytes by additional memory options. The activity within
the CPU is invisible to you.
CPU
Your workstation, a combination of a keyboard and video display,
is your path to the CPU. This chapter is divided into three
sections, each of which describes one of the three possible HP
250 workstations. Based on the drawings below, turn to the
appropriate section to learn about your workstation.
