8-bit acorn hardware • Re: BBC Master 128 Startup Problem

Thanks vexorg! Excuse my lack of knowledge but how would a scope provide more information than a straight forward voltage reading with a multimeter? Thank you.

Because the you will see any non-DC on the supply rail. It should be 5V +/- 0.5V with around 50-100mV of ripple. A multimeter can, in theory, measure the AC component of the DC power rail, but its measurement ability depends a lot on the quality of the meter. An oscilloscope is really the correct diagnostic tool to use.
