Note on Memory Expansion and Microprocessor Modes:
z 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.

z 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.
