Introduction
1.1 OBJECTIVES OF A MICROCOMPUTER DEVELOPMENT SYSTEM.
In the development of any product that includes a microprocessor, there are aspects
which have no parallel either in random logic design or in computer program develop-
ment (the two predecessors of microprocessor product development).
There is no clear cut demarcation between logic which should be implemented
using random logic hardware, or logic which should be implemented with programmed
instructions; that is what makes microprocessor product development unique. A
successful microcomputer development system, such as UNIVERSAL ONE, must
therefore support digital logic development and program creation with equal ease.
If in addition, the product or series of products can benefit from the use of different
microprocessors, a single universal hardware and software development system, of
the configuration of UNIVERSAL ONE, has several easily recognizable advantages:
1. It eliminates the cost of another development system each time a new micro-
processor is to be implemented.
2. It providesa common system for all development, thus eliminating heavy
investments in personnel training and software for multiple systems.
3. It frees the designer to consider any microprocessor-solely on the basis of
its capabilities and cost-effectiveness, rather than because the designer is
locked into a microprocessor from a previous product commitment.
1.2 UNIVERSAL ONE OVERVIEW.
1.2.1 Master/Slave Concept. UNIVERSAL ONE, achieves the required uni-
versality by dividing its operations into two functional areas. Those tasks that are
related to the development system itself are assigned to a master central processing
unit, and those that are prototype-related are assigned to a second, slave CPU. As
many as four different slaves may be installed simultaneously and individually invoked
with a corresponding slave diskette. This mUltiple architecture enables the hardware
to support a particular microprocessor with the addition of a printed circuit card
containing the corresponding slave CPU. Since the master processor need not be
changed to accommodate new slave units, all of the operating system software remain
the same.

The master CPU is responsible for all system services that are not prototype-
dependent, such as:
