ZX Spectrum : Re-coloured

During the development of the ZX Spectrum SE, it was originally planned to replace the ULA (which creates the display) with something a little more advanced. However, it wasn't until nearly a decade later after the ULA was reverse engineered that this actually became possible. ULAplus was finally realized in an FPGA core by Alessandro Dorigatti in February 2011. This core is used in all of the current implementations.
