PROTOTYPE CONTROL PROBES
8080, 6800 EMULATOR PROCESSOR
Two Prototype Control Probe cables are attached to the top edge connectors P2 and P3 of
the Emulator module as shown in Fig. 11-1. Care should be taken that pin 1 of the cable
(red strip) and pin 1 of the edge connector align. Pin 1 is to the left when viewed from the
component side of the module. Press firmly on the cable connectors to seat them properly
into their board edge connector. Before removing the module, make sure that the primary
power to the µProcessor Lab is OFF. Grasp the module ejectors (small white plastic handles
on each upper corner of the module) and pull upward. The ejectors will lift the module free
of the motherboard.
The emulaiion cabie assembiies that enter the center and right cableways (from a front panel
view) on the backpanel of the µProcessor Lab, must be correctly installed in the cable clamps
as illustrated in Fig. 11-2. Make sure the bared ground plane of each cable makes good
contact with the cable clamps to ensure proper grounding.
9900, Z80 EMULATOR PROCESSOR
The Mobile Microprocessor
An eight-foot cable acts as an interface between the prototype circuitry and the Emulator
Processor module. If the microprocessor device remains on the Emulator Processor module,
the eight-foot cable could cause an unacceptable time delay. (The Z80A and 9900 operate
at excess of 1 MHz.) The potential time delay is eliminated by locating the microprocessor
device on a small auxiliary circuit board called the Mobile Microprocessor board.
