A couple of videos below that should be pretty interesting for fans of the good old ZX Spectrum. These are the first two parts in a series, with more major modifications (including making a portable Speccy) coming. Enjoy!
Updated Sunday August 24 2014: post updated with all three parts of the portable Speccy project. Disappointing that we don’t actually see more of the finished project. Kind of amazing that it works at all! Cool stuff though.
