Small update.. Parts now ordered for this.. I'm going to ship the three boards and parts to a place in the UK for assembly as I just do not have time to do it. So hopefully in a few days time I can get the boards back and actually start working on the firmware.

Just as a re-cap, this board is the 68SEC000 test board, so I can see what the maximum speed of the CPU is. I am hoping to get it running at 50-64Mhz.

Even if the CPU cannot manage much more than the 68HC000 PLCC CPU, I will likely still use the SEC simply due to it is smaller, and a proper SMT package. With all the problems I am having with sockets, I have no choice but to move to a direct soldered part anyway. So moving to the 68SEC000 CPU is basically a good move anyway.
