I am lucky and i bought my A1200 when they first come out, and I have got a 1a revision mobo, that seems to work fine with everything. I bought a 175/603e-040/25 of some guy for £60 about two years ago who said the board was ####ed and it worked perfectly on my mobo.
U might think, f off u gloating git. But my mobo has a had a few reapirs on it recently,due to a trace burning out and other things. So I need a new mobo.
Changes of finding one of the first revisions.....Well ive been trying for two years.....
