1-1. PURPOSE OF INTERFACE POD
8080
Section 1
Introduction
The purpose of the 9000A-8080 Interface Pod, hereafterreferred to as the pod, is
to interface any 9000 Series Micro System Troubleshooter to a piece of
equipment employing a 8080 microprocessor.
The 9000 Series Micro System Troubleshooters are designed to service printed
circuit boards, instruments and systems employing bus-oriented
microprocessors. While the architecture of the troubleshooter main frame is
general in natureand is designed to accomodateprocessors with upto 32 address
lines and 32 data lines, the interface pod adaptsthegeneral purposearchitecture
of the 9000 Series to a specific microprocessor, or microprocessor family. The
interface pod adapts the 9000 Series to microprocessor-specific functions such
as pin layout, status/control functions, interrupt handling, timing, size of
memory space, and size of 1/0 space.
1-2. DESCRIPTION OF INTERFACE POD
The pod consists of a pair of printed circuit board assemblies mounted within a
small break-resistant case. A shielded 24-conductor cable connects the printed
circuit boards to the troubleshooter; a ribbon cable and connector provide
connection to the unit under test, hereafter referred to as the UUT.
Figure 1-1 shows the relationship of the pod to the troubleshooter and to the
UUT. Connectionfrom the pod tothetroubleshooter is via a front-mounted 25-
pin connector. Connection to the UUT is made by plugging the ribbon cable
plug directly into the microprocessor socket. The UUT microprocessor socket
gives the troubleshooter direct access to all system components which normally
communicate with the microprocessor.
The pod contains a 8080 microprocessor and the supporting hardware and
control software required to:
• Perform handshaking with the troubleshooter
1-1

8080
• Receive and execute commands from the troubleshooter
• Report UUT status to the troubleshooter
• Emulate the UUT microprocessor
The pod is powered by the troubleshooter, but is clocked by the UUT clock
signals. Using the UUT clock signals allows the troubleshooter and pod to
operate at the designed operating speed of the UUT.
Logic level detection circuits are provided on each line to the UUT. These
circuits allow detection of bus shorts, stuck-high or stuck-low conditions, and
any bus drive conflict(two or moredrivers attempting to drive thesame bus line).
Over-voltage protection circuits are also provided on each line to the UUT.
These circuits guard against pod damage which could result from:
• Incorrectly inserting the ribbon cable plug in the UUT microprocessor
socket.
• UUT faults which place potentially damaging voltages on the UUT
microprocessor socket.
The over-voltage protection circuits guard against voltages of+ 12 to -7volts on
any one pin. Multiple faults, especially of long duration, may cause pod damage.
A power level sensing circuit constantly monitors the voltage level of the UUT
power supplies. If any UUT power supply rises above or drops below an
acceptable level, the pod notifies the troubleshooter of the power fail condition.
A self test socket provided on the pod enables the troubleshooter to check pod
operation. The self test socket is a 40-pin zero-insertion force type connector.
The ribbon cable plug must be connected to the self test socket during self test
operation. The ribbon cable plug should also be inserted into this socket when
the pod is not in use to provide protection for the plug.
