INTRODUCTION
This section supports the Z80A Emulator Processor and Prototype Control Probe as well as the newer Z808
Emuiator Processor and Probe. While the Z80A Emulator Processor can emulate only Z80 and Z80A
microprocessors, the Z808 Emulator Processor can emulate the Z80, Z80A, and Z808 microprocessors.
In this section, the term "Z80 emulator" is used in presenting information that applies to both the older Z80A
emulator and the newer Z808 emulator. The term "Z80A emulator" is used for information that applies only
to the Z80A Emulator Processor. The term "Z808 emulator" is used for information that applies only to the
newer Z808 Emulator Processor.
This Emulator Specifics section is to be inserted into Section 7 of the 8550 System Users Manual (DOS/50
Version 2) or the 8540 System Users Manual. It explains the features of the 8550 and 8540 systems that are
unique to the Z80A and Z808 Emulators. Throughout the section, "your System Users Manual" refers to the
8550 System Users Manual or 8540 System Users Manual. The Z80 Demonstration Run is designed to be
used with Section 1 (the Learning Guide) of your System Users Manual; the rest of this section contains
reference material.
GENERAL INFORMATION
Emulator Hardware Configuration
Throughout this Emulator Specifics section, the term "Z80 emulator" refers to a Z80 Emulator Processor
boad configured with a Z80 Prototype Control Probe or mobile microprocessor. In emulation Mode 0, the
mobile microprocessor may be inserted directly into the emulator board. In Modes 1 and 2, the mobile
microprocessor must be installed in the prototype control probe and the prototype control probe must be
connected to both the emulator and your prototype. For instruction on installing the emulator board, mobile
microprocessor, and probe, refer to the Z80 Emulator Processor and Prototype Control Probe Installation
Service Manual.
Microprocessors Supported
The Z80A emulator emUlates the Zilog, Z80 and Z80A microprocessors. The Z808 emulator emulates the
Zilog Z80, Z80A, and Z808 microprocessors.
Emulation Modes
The Z80 emulator supports Emulation Modes 0, 1, and 2, as described in the Emulation section of your
System Users Manual. The Z80 emulator supports service calls (SVCs) in all three modes.

General Information zao Emulator Specifics Users
zaOA Clock Rate
In Mode 0 emulation, the emulator clock rate is 2 or 4 MHz, depending on the setting of jumper J1. In Mode
1 emulation, the maximum recommended rate for the prototype clock is 4 MHz.
zaOB Clock Rate
In Mode 0 emulation, the emulator clock rate is 4 or 6 MHz, depending on the setting of jumper J3002. In
Mode 1 emulation, the clock rate of 6 MHz may be used only with 8500-series systems. At this 6 MHz rate,
one wait state will be inserted.
NOTE
When used with the Trigger- Trace Analyzer (TTA) or the Real- Time Prototype Analyzer (RTPA), the
ZaOB Emulator Processor provides an output that is one-half of the emulator operating clock rate.
Therefore, the clock count stored in the TTA or RTPA buffers will be one-half of the actual emulator
clock count.
Symbolic Debug
The l80 emulator supports the use of symbolic debug.
EMULATOR-SPECIFIC COMMANDS, PARAMETERS, AND
DISPLAYS
SEL-Selecting an Emulator
The SEL (SELect) command allows you to select the emulator you want to use with your system. The
following command line selects the l80 emulator and assembler:
> SEL zao
Byte/Word Parameter
Several commands offer you the choice of operating on memory on a byte-oriented or word-oriented basis.
In affected commands, this choice is represented by the -B or -W parameter. For the l80 emulator, the
default value is -B (Byte).
MAP-Mapping Memory
The l80 addresses a 64 K memory space, arranged in 512 blocks of 128 bytes each. The MAP command
enables you to assign blocks of memory to either program memory or prototype memory, and to designate
blocks of program memory as read-only. Refer to the Command Dictionary for details on the syntax. param-
eters. and use of the MAP command.

zao Emulator Specifics Users Commands and Displays
Setting Breakpoints
The zao emulator allows you to specify up to two breakpoints with the BK command.
Memory Allocation Commands
The Memory Allocation Controller (MAC) option cannot be used with the zao
emulator. The zao
does not
use the MEMSP command, and does not support memory space qualifiers or expressions. The zao
emula-
tor supports the AL (Allocate) command, as described in the Command Dictionary of your System Users
Manual. The DEAL, MEM, and NOMEM commands are not supported.
Port Commands
The zao emulator does not support the RD or WRT commands.
CONS Command Modes
The zao
emulator supports the FET mode of the CONS command of the Trigger Trace Analyzer. The zao
does not support the EMU mode of the CONS command.
Register Designators
Table 7C-1 alphabetically lists the symbols used by DOS/50 and OS/40 to designate the registers and flags
used by the zao.
The table provides the following information for each symbol:
