The thing I loved about Spectrum was game loading graphics from tape. Spectrum had a very strange video memory layout, so the bitmap would load first into different thirds of the screen (but still all monochrome). And then at the end the attributes (which were much smaller due to the 8x8 size) would load almost instantly, "painting" the monochrome image in a final splash! So this is very nostalgic for sure.

And the funny thing is, I like the spectrum renders better than the "perfect" ones from a modern computer :-)
