First post from me, but have been watching loads of Dave's vid's over the past couple of weeks and loving them all for the "edutainment" value.

I was almost hoping for a LHC teardown in this one when I saw the mention of it, but I guess if Dave was let loose on that beast, we'd probably never see him again!

That cruddy stuff on the Canon calc pcb looks a bit like fag (cigarette) ash, although it seems to match up with the black strip on the reverse of the LCD - so it may just be the remains of some sort of adhesive that has gone manky after what must be almost a third of a century of use.
That Teletype tape from Kjetil in Norway was pretty cool too, also the Hexbugs; I'll have to get a few of those for my niece & nephew who live in Cape Town!
