The whole point of this thread so far has been the monitoring of a pin or two... not the contents of multiple outputs... perhaps shift registers... and the best tool for the job. My point is that both scopes serve different purposed and are in many ways better suited to a specific task, digital works better for digital and analog works better on analog signals. Looking as t Pure Sine Wave that I am Listening to and seeing "Stuff" that I can't hear but is clearly displayed on a cheap digital scope is somehow wrong... a Digital scope is more valuable for absolute level and time measurements both immediate and through storage.
Neither task is well performed by a Logic Analyser... and you couldn't fix your stereo easily with a logic analyzer But you could use either a digital or an analog scope for that purpose.. IMO
