Preface: Microprocessor Support Documentation
This instruction manual contains specific information about the TMS 501 Z80
microprocessor support package and is part of a set of information on how to
operate this product on compatible Tektronix logic analyzers.
If you are familiar with operating microprocessor support packages on the logic
analyzer for which the TMS 501 Z80 support was purchased, you will probably
only need this instruction manual to set up and run the support.
If you are not familiar with operating microprocessor support packages, you will
need to supplement this instruction manual with information on basic operations
to set up and run the support.
Information on basic operations of microprocessor support packages is included
with each product. Each logic analyzer has basic information that describes how
to perform tasks common to support packages on that platform. This information
can be in the form of online help, an installation manual, or a user manual.
This manual provides detailed information on the following topics:
H Connecting the logic analyzer to the system under test
Manual Conventions
H Setting up the logic analyzer to acquire data from the system under test
H Acquiring and viewing disassembled data
H Using the probe adapter
This manual uses the following conventions:
H The term disassembler refers to the software that disassembles bus cycles
into instruction mnemonics and cycle types.
H The phrase “information on basic operations” refers to online help, an
installation manual, or a basic operations of microprocessor supports user
manual.
H In the information on basic operations, the term XXX or P54C used in field
selections and file names must be replaced with Z80A. This is the name of
the microprocessor in field selections and file names you must use to operate
the Z80 support.
H The term system under test (SUT) refers to the microprocessor-based system
from which data will be acquired.
TMS 501 Z80 Microprocessor Support Instruction Manual

Preface: Microprocessor Support Documentation
H The term logic analyzer refers to the Tektronix logic analyzer for which this
product was purchased.
H The term module refers to a 68/102/136-channel or a 96-channel module.
H Z80A refers to all supported variations of the Z80 microprocessor unless
otherwise noted.
H A tilde (~) following a signal name indicates an active low signal.

TMS 501 Z80 Microprocessor Support Instruction Manual
Getting Started
Support Description
This chapter provides information on the following topics and tasks:
H A description of the TMS 501 microprocessor support package
H Logic analyzer software compatibility
H Your system under test requirements
H Support restrictions
H How to configure the probe adapter
H How to connect to the system under test (SUT)
The TMS 501 microprocessor support package disassembles data from systems
that are based on the Zilog Z80 microprocessor. The support runs on a compatible Tektronix logic analyzer equipped with a 68/102/136-channel module or a
96-channel module.
Refer to information on basic operations to determine how many modules and
probes your logic analyzer needs to meet the minimum channel requirements for
the TMS 501 microprocessor support.
The TMS 501 supports the Z80 microprocessor in a 40-pin DIP package.
A complete list of standard and optional accessories is provided at the end of the
parts list in the Replaceable Mechanical Parts chapter.
To use this support efficiently, you need to have the items listed in the informa-
tion on basic operations as well as the following manuals:
H Z80-CPU/Z80A-CPU Technical Manual, Zilog (03-0029-00)
H Z80 Microcomputer System Programming Manual, Mostek (MK78515)
Information on basic operations also contains a general description of supports.
Logic Analyzer Software Compatibility
The label on the microprocessor support floppy disk states which version of logic
analyzer software the support is compatible with.
TMS 501 Z80 Microprocessor Support Instruction Manual
1–1
Getting Started
Logic Analyzer Configuration
To use the Z80 support, the Tektronix logic analyzer must be equipped with
either a 68/102/136-channel module, or a 96-channel module at a minimum. The
module must be equipped with enough probes to acquire channel and clock data
from signals in your Z80-based system.
Refer to information on basic operations to determine how many modules and
probes the logic analyzer needs to meet the channel requirements.
Requirements and Restrictions
You should review the general requirements and restrictions of microprocessor
supports in the information on basic operations as they pertain to your SUT.
You should also review electrical, environmental, and mechanical specifications
in the Specifications chapter in this manual as they pertain to your system under
test, as well as the following descriptions of other Z80 support requirements and
restrictions.
System Clock Rate. The microprocessor support product supports the Z80
microprocessor at speeds of up to 20 MHz
DIP testclip adapter, the maximum supported clock speed is reduced to 6 MHz.
Configuring the Probe Adapter
There is one jumper on the probe adapter used to configure the probe adapter for
disassembler operation or to acquire timing data.
The Disassembly/Timing jumper (J1203) should be placed in the NORMAL
position to acquire disassembled data, and in the TIMING position to acquire
timing data. Table 1–1 shows how to position this jumper depending on the type
of clocking you’re using and the type of window you want to view.

Connecting to a System Under Test
Before you connect to the SUT, you must connect the probes to the module.
Your SUT must also have a minimum amount of clear space surrounding the
microprocessor to accommodate the probe adapter. Refer to the Specifications
chapter in this manual for the required clearances.
The channel and clock probes shown in this chapter are for a 68/102/136-channel
module. The probes will look different if you are using a 96-channel module.
The general requirements and restrictions of microprocessor supports in the
information on basic operations shows the vertical dimensions of a channel or
clock probe connected to square pins on a circuit board.

Getting Started
DIP Probe Adapter
To connect the logic analyzer to a SUT using a DIP probe adapter, follow these
steps:
1. Turn off power to your SUT. It is not necessary to turn off the logic analyzer.
CAUTION. Static discharge can damage the microprocessor, the probe adapter,
the probes, or the module. To prevent static damage, handle all of the above only
in a static-free environment.
Always wear a grounding wrist strap or similar device while handling the
microprocessor and probe adapter.
2. To discharge your stored static electricity, touch the ground connector located
on the back of the logic analyzer. Then, touch any of the ground pins of the
probe adapter to discharge stored static electricity from the probe adapter.
3. Place the probe adapter onto the antistatic shipping foam to support the probe
as shown Figure 1–2. This prevents the circuit board from flexing and the
socket pins from bending.
4. Remove the microprocessor from your SUT.
5. Line up pin 1 on the microprocessor with the pin 1 indicator on the probe
adapter board.
CAUTION. Failure to correctly place the microprocessor into the probe adapter
might permanently damage all electrical components once power is applied.
6. Place the microprocessor into the probe adapter as shown in Figure 1–2.
