Hi
Just to let you know I have altered the PCW exapansion port pinout: http://www.cpcwiki.eu/index.php/Amstrad_PCW_Expansion_Port
..because it looks like /MDIS and VIDEO are the wrong way round. As I have used the video signal on my uIDE expansion port adapter cards, and in my design VIDEO is connected to pin 46 - and it works - I think that is evidence that the page is wrong. Attached is a section of my schematic showing how the pins are wired.
Kudos to TynH for spotting this discrepancy.
Cheers
