The Apple II’s CPU clock has jitter or a glitch. This problem shouldn’t be new—it has been current since its unique design in 1977!
Bald Engineer makes use of an oscilloscope to point out how usually the glitch happens and correlate that jitter to its supply—which is beneficial when you’re not testing 40-year-old units. The gadget below check (DUT) on this video is the Mega IIe undertaking. It’s a totally suitable Apple IIe constructed across the Mega II chip.
