I absolutely love my Tandy Model 100. But let's face it - it's a laptop from the early 80s, and it run as early-80s speeds. But fortunately, there's a new experimental mod that lets you run the Model 100 at a whopping 5MHz. It's not an easy one, though, because there are a lot of downstream impacts when you start messing with the system clock.
In this video, I'll take you through the process of installing the clock doubler mod, and I'm going to explain how it works along the way. We'll talk about some of the nuances of the Model 100, as well as intricacies of the timing architecture.
