The onebit vacuum tube computer is back baby! Well, kind of. The reason it’s been so long since we last took a look at it is because I’ve been doing some serious thinking about how best to build the paper tape. I experimented with a lot of ideas before finally settling on a “Keep It Simple Stupid,” approach. Fair warning, this episode is primarily to get everyone back up to speed on the project and let y’all know what direction we’re now headed in for the paper tape. The good news is, we have a gameplan, so things should start shaping up real soon!
