Hi, I have another one offer for you. If you have universal programmer, talk with ve ndor to make this pin swapping by software. If you can't find enough agreeable c ompany, try http://www.elenc.com/lprog_uk.htm for programmer and http://www.elen c.com/algor_uk.htm for mentioned service (its free !!). They make all, what you need. (I have one and I know, what I saying). Jan.
