It's funny you should mention that... I recently got a new LCD TV (a nice Samsung 32", unfortunately not "Full HD" though...) and just the other day I thought I would dig Sam out and see how it looks on it. It's been a while since I've used my real Sam and it seems my floppy has finally died (an original Citizen; it sounds like the usual stretched drive belt problem, but that's another story), so I was restricted to playing about in BASIC for a bit. Anyway, it seems my TV doesn't realise the signal is not interlaced! With a static display there is nothing to show it, but with fast movement (I did a ROLL of a small area in a loop with PAUSE 1) it is clear that the TV is interpreting pairs of Sam frames as the two fields of a single interlaced frame. In an extreme example I had a pair of ROLLs shifting an area left then right and the TV shows a static image with a nice comb effect. Makes me want to dig out those Fred issues with "interlaced" images on them to see how they look. If only my drive worked... (Colin, do you still have spare belts? :-) Dave (de-lurking after aaaages).
