IMPORTANT
Note on Memory Expansion and Microprocessor Modes:
• To use memory expansion or microprocessor mode, be sure to set pins RDY*,
HOLD* and NMI* so that they are not active at start-up. Otherwise the emulator
system will not start up correctly.
Note on CLOCK LED:
• If CLOCK LED does not turn on, check the following:
(1) Immediately after starting PC7501 (before starting the emulator debugger)
--> Check if the oscillation circuit within the PC7501 emulator main unit
oscillates normally.
(2) After starting the emulator debugger (after setting the Init dialog box)
--> Check the oscillation circuit set in the Init dialog box oscillates normally.
• If this LED does not light, check the voltage of the target system.
• Check power is supplied to all the power terminals.
• When the target system is not connected, this LED does not light.
