     A few years ago I did a ProDOS STARTUP program selector which 
includes a Time/Date display and shows current system speed as a multiple 
of 'Normal'. For example, for a 10MHz Zip-GSX system set for max speed, 
the display shows "x10". If Zip speed is set to 70%, it shows x7, etc..

     The routine which samples speed is part of a wait-for-keypress 
loop. The way it works is to CALL the ASCII Time/Date tool save the last 
Seconds digit and start counting number of cycles in-out of a delay 
routine which includes CALLs to the Time/Date tool to check the last 
Seconds digit. When the digit changes or a key is pressed, the routine 
exits. The count is used to figure the speed which is then displayed.
  
     I'll upload the program as SPEEDGS.SHK to the 1WSW area on Ground 
later on today.
