Impressive stuff there, uni! Thanks for the link to the 128MB SIMM. I may need to find an alternative, though, as their shipping costs (~£25) are a bit steep for me, given that I would need - at most - one or two chips. In any case, I found this, but can't tell if it's double-height. In which case would it fit in the LC475?
