The PCW adapter is called a '''CPS8256''' and it has both serial and parallel ports. It is not compatible with the PCW 9512.
However, building on the ''Z80 bus'' concept employed by uIDE, I have designed completed the design of a 5 slot bus board and I plan to produce a serial adapter to plug into it that is a clone of the CPS8256. The status of the serial adapter is that it is nearly ready for prototyping. Other extensions should follow, so keep an eye on the forum for developments.
