Due to other, exciting distractions (which I will mention in a later post), I haven't had a chance to keep the blog up to date. Still, work progresses on the boat, and that's the important part. Last month, with the keel now in its new position about 30mm further back along the hull, and sealed into place, it was time to add the electronics board.

When National Semiconductor and AMD stopped making Geode chips, the guys at PC Engines had to stop making their very popular WRAP board. I still have a few of them tucked away, for emergencies such as this.
