<GRIN> What, like a logic probe...?
I don't actually have a logic analyser myself (annoyingly), and tend to
reach for my logic probe long before I resort to digging out my 'scope. I
find mine indispensible.
If the OP is in the UK, then Maplins do a nice one for £15 (which is less
than I paid for mine back in 1980).
