Hello,

From my experience, I've not found it necessary to use a socket when
building a pcb board prototype. The sockets are usually quite large and
costly and you have to design the pcb to handle them. I try to have any bugs
worked out before building pcbs.

My technique is (usually) to use a STK500 and STK501 to carry the m128
processor and wire up the other things by wirewrap, cables, or whatever to
get a platform to do early software and hardware check out.

When I get to building an actual pcb board, it is not necessary to use a
socket on the pcb as the hardware and software are pretty well checked out.
There is always, it seems, changes required for the production board but it
usually is something I forgot or a value change of component.

Best of luck,

Jim
