We have a daughter board here that plugs into the header
and brings out a serial line. I've only seen one of these
devices, and it follows whoever is working on the latest
hardware/booter/kernel debugging puzzle on the 2700.
Is it a pretty simple board, with an SCC and some glue,
so an intrepid explorer with a breadboard could probably
build one. I just asked one of our hardware guys if he
has a skematic lying around. Needless to say, it was only
used for internal debuging, so there is a chance that the
files are lost to antiquity. More news later.
