PURPOSE OF THE INTERFACE POD The 9000A-Z8000 Interface Pod (hereafter referred to as the Pod) interfaces any Fluke 9000 series Micro-System Troubleshooter (hereafter referred to as the Troubleshooter) to equipment using one of the Z8000 family of microprocessors. The Troubleshooter services printed circuit boards, instruments, and systems employing microprocessors. The 9000A-Z8000 Interface Pod adapts the general purpose architecture of the Troubleshooter to the specific architecture of the Z8000 microprocessor family. The Pod adapts such microprocessor-specific functions as pin layout, status/control functions, interrupt handling, timing, and memory and I/O addressing. The 9000A-Z8000 Interface Pod can accommodate all four members of the Z8000 family: Z8001, Z8002, Z8003, and Z8004. An adapter is provided for use with the 40-pin Z8002 and Z8004 versions. A switch on the Pod selects between Segmented Memory Z8001 and Z8002 versions, and Virtual Memory Z8003 and Z8004 versions. Unless otherwise specified, references to the “Z8000” in this manual refer to any of the Z8000 family of microprocessors. DESCRIPTION OF POD Figure 1-1 shows the communication between the Troubleshooter, the Pod, and the Unit-Under-Test (hereafter referred to as the UUT). Cables connect the Pod to the Troubleshooter via a front-panel connector and to the UUT through the microprocessor socket. The external features of the Pod is shown in Figure 1-2. Internally, the Pod consists of a pair of printed circuit board assemblies mounted within an impact-resistant case. The Pod contains a Z8000 family microprocessor along with the supporting hardware and control software that is required to do the following: 1. Perform handshaking with the Troubleshooter. 2. Receive and execute commands from the Troubleshooter. 3. Report UUT status to the Troubleshooter. 4. Allow the Pod microprocessor to operate the UUT.
