Testing the clock with the LogicDART
Testing the 1MHz "phase2" clock for the SID chip (6581), using the HP LogicDART. I've used a 16MHz clock oscillator module that I happened to have (desoldered from some long-forgotten PCB) and divided it down with a 74HC393 chip. The LogicDART is a hand-held three channel logic analyser with additional modes for voltage and frequency measurement, and for continuity and diode testing.
