PREFACE
This manual describes the 990 Proto typing 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 Proto typing 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 the system, and the hardware components that support it.
II. System· Installation and Operation - Gives the sources of information on unpacking,
installing and operating the supporting hardware, with appropriate references. Step-by-
step procedures for installing the software, loading the software modules, and operating
the modules are included. Interrupts and single instruction execution are explained.
III. Debug Monitor - Describes the I/O operations, loading methods, debugging modes,
and operator commands of the debug monitoT. Debugging techniques are discussed at
length. The commands are explained and detailed descriptions of each of the com-
mands are included. Detailed descriptions of the supervisor calls follow.
