I hope someone can help me.....
I remember a thread from a while back where someone linked a clever little DB25 adaptor which you could take the top off and link whichever pins on the 'in' to whichever pins on the 'out' side. I think it was done by small press in pieces of bendy wire but can't be certain.
I thought it was in response to one of my previous posts about X,Y reversal but it appears to not be the case....
