	Set reader to FREQ, put black probe to GND, red probe to 38 / 39 to measure CPU clock		Set reader to FREQ, put black probe to GND, red probe to 38 / 39 to measure CPU clock.<br>
			20100906 Note from Jonathan Gevaryahu: check pin 39 (XTAL) of the 6809; if this pin is grounded, the clock comes in purely through pin 38 (EXTAL) and can be measured there. If the pin is NOT grounded, measure pin 34 (E) or pin 35 (Q) and multiply the resulting frequency by 4 to get the actual clock frequency the chip is being fed, since if XTAL is not grounded, measuring on EXTAL or XTAL may affect the clock to the chip and throw off your measurement.
