What is this unused port for on A1200 mobo?
« on: September 01, 2008, 08:57:25 PM »
I saw this picture http://www.amiga.org/gallery/images/4660/1_4001.jpg

earlier and noticed the surface-mount solder pads to the right of the picture, near the kickstart sockets (labelled U8?). What was this used/intended to be used for please?

Thanks.

Thanks for clarifying it. I imagine that it is much easier to add a co-pro to a plug-in accelerator.

As for cost, adding an FPU to an unexpanded A1200, plus the work to get it soldered on perhaps isn't worth it. I would spend a bit more and buy at least a fast-RAM expansion (if I didn't already have an A1230 Mk IV).
