  • 64k speccydoes anyone have instructions on how to use the extra 16k found in some spectrums?

    The other thing you can do is fit a 16kB SRAM instead of the ROM and have a 64k all RAM spectrum, which winston did with one of his 48k machines :)

    I know this isn't remotely what the OP was asking, but it is pretty cool anyway :)
