The number of controls and indicators have been minimized to
facilitate
system use.
Only the keylock ON/OFF switch, the
RESET and START switches, and the AC power switch are neces-
sary
to
power
up and maintain the S8000.
Refer to Figure
1-2 for control and indicator locations.
Controls
for
the
optional Lear Siegler ADM-3l Data Display Terminal include a
brightness/contrast control knob
and
an
AC
power
ON/OFF
switch.
The resources of the S8000 are controlled by the
ZEUS
Ker-
nel.
The
Kernel
or
the operating system provide process
management, file management, input/output (I/O)
processing,
and
increased
program
functionality with compatible file,
device, and interprocess I/O.
ZEUS is a multi-user, multitasking operating system consist-
ing of a hierarchical file system for efficient file organi-
zation and a comprehensive command language.
A communica-
tion
program
allows the S8000 to interface with other ZEUS
or UNIX-based systems.
Also, with ZEUS, it is
possible
to
communicate with emulation devices and development modules.
ZEUS development tools include extensive language
capabili-
ties such as C, Pascal, PLZ/SYS, PLZ/ASM, a compiler-writing
system, and a general
purpose
macroproCessor.
Additional
enhancements
to
the development system include a full CRT-
oriented text editor, text processing, spelling error detec-
tion, and document formatters for the optional printers.
