GZ logic level shifter assembly notes

Now I am using 2 ULN2803 octal darlington pairs to logic level shift up the gz_test's 8 stage counters.  I am using LEDs to indicate the status of the ULN2803 output pins.  I found the gz_test.c's slow master clock options 152KHz a bit too slow at the last stage 0.07Hz, and the 9.6MHz a bit too fast for my eyes at the last stage of4.58Hz.  So I am now using a 1MHz crystal clock as the master clock for gz_test to count down.  Now it is easy the eyes to catch the LED toggling, fromabout 60 Hz to 0.5Hz.
