In 1956 Librascope released the LGP-30, a truly wild machine. It was, for the time, the most simple and cheap machine that could actually be useful. It was the size of a desk when contemporary machines took up small rooms. It plugged into a normal wall outlet while other machines requires special power feeds. It was, perhaps, the first hint of a personal computer. And at its heart was a magnetic drum that only a true programmer could love.

I'm wrapping up my dive into Prolog with... Prolog itself! This episode I'm actually covering the development of Prolog, using all the natural language processing lore we covered last time. Along the way we will see how Prolog developed from a set of tools, and how those tools were generalized into a useful language.

I've been told I need to do an episode about Prolog. Well, here's the start of that process. To talk about Prolog we first need to come to grips with natural language processing, it's tools, and it's languages. This episode we are doing just that, going from ELIZA to Planner ro SHRDLU in an attempt to figure out how AI was first taught human tongues, where smoke and mirrors end, and where facinting programming begins.

Space is cool, in all meanings of the word. Not only is it wondrous, vast, and fascinating, it can also be a cold place. It's also a very useful place to put things. This episode we are looking at the first practical use of space: communication satellites.

I don't usually cover video games. When I do, you know it's for a weird reason. This episode we are looking at the Atari VCS 2600, it's strange hardware, and how it fits into the larger story of the rise of microprocessors. These new tiny chips were already changing the world, but they brought along their own problems.

What really is the deal with microcontrollers? Are they just little computers... or are they something totally different? This episode we are looking at the development of the microcontroller through the history of the TMS1000.

This episode we pick back up where we left off. We are looking at the roots of the Mundaneum, the applications of the Universal Decimal Code, and how it call connects to hypertext.

The Internet is the closest we've come to a universal store of all human knowledge. However, it's not the first pass at this lofty goal. In this episode(and the next) we are looking at the Mundaneum, a project started in the 1890s to address the information problem. How is it connected to the larger story of hypertext? And how can this older project inform our views on the information problem? Selected sources: https://www.ideals.illinois.edu/items/4184 -- Selected Essays of Paul Otlet

Back in episode 90 I made a passing reference to the Cyclops, the first consumer digital camera. It's this masterstroke of hackery that uses a RAM chip as a makeshift image sensor. In this episode I'm coming back around to the Cyclops and taking a look at the origins of digital imaging in general.

The Apple III was a pretty slick machine... in theory. From a lack of launch software, to strait up hardware failures, Apple's 3rd computer didn't really win in the market place. Why was that? Was the machine setup for failure from the start? Was it's case really designed before it's motherboard? When it comes to the III there's a surprising amount of folklore to untangle.
