<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).
