This manual describes the 990 Prototyping System and
gives
instructions for installing and
operating
it
on the Model
990/4
Computer.
It
provides detailed descriptions
of
the individual
modules that comprise the system software and includes techniques for using them.
This publication
is
intended for users
of
the 990 Prototyping System package: users who are
developing applications programs for the 990/4 Computer, the 990/10 Computer, and the
TMS9900 Microprocessor, and users who generate and test read-only memory (ROM) resident
programs for use with the TMS9900 Microprocessor.
The information in this manual is divided into the following sections:
i. General Description -Briefly describes the 990 Prototyping System Software, the
modules. in
