I spend hours and hours to get it running, tried several different IC's (I expected speed problems etc) all with no result......... 1.37MHz in ......NOTHING out................ Have you checked the waveform produced by the oscillator ? With 4000 series CMOS you need almost rail-to-rail driving signals. May be a 74HCT... would have been more suitable. 73 Alberto I2PHD |
