Actually this seems to be a complete PC minus the keyboard... the CPC being quite only a terminal/keyboard then, or is it not ?
The article lacks a few infos :
*Is it a CGA display ? does it uses the CPC monitor or does it need a proper PC monitor ?
*Can it use the CPC diskDrive while in PC mode ?
*Can it use the CPC's sound capabilities ?
Is the CPC mostly a Keyboard and a Graphic+Sound extension card...?
