ACT Apricot keyboards, or infra-red japes

Hi folks, Recently I've picked up the bits of the infra-red Apricot keyboard that Jules investigated at my place and left in bits all over one of my sofas :) It's a membrane activated by springs and quite a lot of the keys don't register with the host machine which in wired keyboards points to a dodgy membrane.....however, in this case there might also be some issue with the infra-red emitters, so short of dragging a digital video camera down to my southern home is there a way of watching the infra-red emitters to see if they're working OK? I know CCD based video cameras can see infra-red...... Apologies in advance if this message appears garbled, I'm using an awfully off-topic Mac G4 with OSX 10.2 and I'm not used to its settings yet :) The machine was going to be dumped yesterday because 'it doesn't work'..........oh yes it does :D Cheers, a
