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.
Could be considered as PCWclassic+sound add-on AY chip board+color video expansion one.
Or could be considered as PCWclassic+sound add-on AY chip board+color Time ago definition, decades ago kind of imaginary computer, now reality. Actually extended system derived from the Amstrad PCW / Schneider Joyce. It has colour video expansion oneand sound capabilities that the classic PCW lacked.
Based on certain features that the '''[[ANT]]''' project, (Arnold Number Two) from the Amstrad/Locomotive development team led by Ronald Perry, would also possess.
Nowadays emulated and FPGA-ed too.
John Elliot's PCW '''Joyce''' emulator supports colour with JOYCE 800x600 driver.

In the evolution of '''Habisoft's CP/M Box''' emulator and its research into the PCW system arose the idea to clone the '''dk'Sound''' board (existed at that 80´s time as add-on). This had the AY sound chip. And later, thanks to FPGA technology, the PCW was equipped with an accessory that would enable colour video: '''ColorIN Board'''.
Historically, only one commercial program, published by Ocean, ''"HeadOverHeels"'' by Ritman and Drummond, supported the AY chip on the PCW.
Habisoft published a series of ports from CPC that expanded the PCW library with more sound: ''Abbey of Crime''; ''Hero Quest''; ''Knight Lore''; ''Pac Mania''; ''Spirits''.

Later, it standardized the possibility of ports from the ZX Spectrum to PCW: ''Movie''; ''Fat Worm''; ''Nonamed''; and ''Phantomas2/Vampire'', which used the PCW's buzzer as the Spectrum's beeper. Some of these also incorporated AY music.
The conversion trail was followed by Kachorro in its Spectrum ports of ''Barbarian'', ''Coliseum'', and ''Xecutor''.
Port $80 is used to send a value to select a register. Port $81 is for associated data; both support reading and writing. Similar to the operation of integrated circuits such as the PSG or a VDP, it allows sending many values with a minimal interface.

This is how '''KachorroSoft''' created the incredible colour ports of '''AMC''' and '''MadMixGame''' with graphics from the CPC; '''Phantis''' from MS-DOS CGA and CPC; and '''Hundra''' from the ZX Spectrum. But with new colour palettes.
* PCW Plus enables fantastic '''loading screens''' never seen before on 8-bit systems.
Color and sound enhanced versions of '''Batman''' and '''Head Over Heels''' will follow later. Showcasing the capabilities of the PCW Plus system
* PCWplus technical specifications add too: joystick dk'Tronics and '''DAC sampler sound'''.
* '''Backward compatibility''' with the classic PCW is maintained in the software.
