scopes [was: how to troubleshoot? ...]

[harry]

The Z feature of a scope lets you control intensity modulation. You
make the trace brighter and dimmer. It can be used to blank the
retrace if you want to construct your own timebase... or if you put
a squarewave in it can act like a "strobe" and freeze the rotation of
lissajous patterns.

Include it in your oscillators if you want an oscilloscope light show !!!
