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'''.

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''.
