I have a system 80b (genesis) that is not booting. I havent used an oscilloscope much at all before but i borrowed one to measure the crystal oscillator and data/adr lines on the cpu. 5V is up and working. When I measure on Z3 pin 6 i get a reading that jumps between 330khz and 600khz. I thought that i would get a reading of 3.57mhz here, if i measure after the Z2 divider on pin 8 I get 330khZ steady where i would assume i should have 900khz.
Since I havent used an oscilloscop much before i was wondering if someone could verify that i should have 3.57khz coming out of z3 pin 6 or 900khz coming out of z2?
Update: error on my side with the oscilloscope, it's working just fine at 3.57mhz
