I didn't get much of an opportunity like I hoped for after my first entry to continue working with my Mattel Aquarius collection through this past weekend, but I did get the stuff cleaned up, a bit better organized, and also cataloged, which I'll share in this post. I'm now at least at a good point where I can dive right in, and thanks to suggestions from some of our members, like Rowdy Rob, I also have something of a plan of how I want to share videos and other content that give a sense of working with the computer before I move on to other stuff.
