I think I might tear my SX Logic Analyser apart and make it a little more useful.. I'm thinking along the lines of a handheld mixed-signal scope - eight digital inputs, one analogue input, 50MHz max sample rate, and a bit of other stuff too. Analogue bandwidth will likely be around 10MHz or so - which should be good enough for most debugging work (if you're doing anything faster than 50MHz, you've probably got a Damn Fast(tm) logic analyser already). Think "HP LogicDart, but more powerful". But I need to get my NiMH charger working first - the family are whining about the cost of AAs again...
