This is time ago definition, kind of imaginary computer, actually enhanced extended system (nowadays emulated and FPGA-ed) derived from the Amstrad PCW / Schneider Joyce. It has colour video and sound capabilities that the classic PCW lacked.
Or could be considered as PCWclassic+sound add-on AY chip board+color video expansion one.
Based on certain features that the '''[[ANT]]''' project, (Arnold Number Two) from the Amstrad/Locomotive development team led by Ronald Perry, would also possess.
