Welcome to Advent of Computing, the show that talks about the shocking, intriguing, and all too often relevant history of computing. A lot of little things we take for granted today have rich stories behind their creation, in each episode we will learn how older tech has lead to our modern world.

    The IAS Machine

    The first batch of digital computers emerge directly following WWII. The hallmark of this generation is uniqueness: no two computers are the same. However, there is a machine that bucks that trend. The IAS Machine, built in Princeton in the late 1940s, served as the inspiration for at least a dozen later computers. But how similar were these Princeton-class computers? What exactly was so special about the IAS Machine? And how does good 'ol Johnny von Neumann get tied up in all of this?

    What can Lunar Lander tell us about FOCAL?

    Lunar Lander is one of the best loves video games of all time. The game was created in 1969 as an homage to the recent Apollo 11. From there it would only spread. Just about anything that can print text has it's own version of Lunar Lander. The early history of this game is mixed up with something weird: two nearly identical programming languages. Today we will be using the history of Lunar Lander as a good excuse to look at an obscure tongue called FOCAL. This language is so close to BASIC that direct line-by-line translation is possible. But are the two connected?

    The Intel 286: A Legacy Trap

    In 1982 Intel released the iAPX 286. It's was the first heir to the smash-hit 8086. But the 286 was developed before the IBM PC put an Intel chip on every desk. It's design isn't influence by the PC. Rather, it reaches further into the past. Today we are looking at the strange melding of old technology, new ideas, and compatibility that lead to the 286.

    INTERCAL RIDES AGAIN - Restoring a Lost Compiler

    In 1973 the world caught it's first glimpse of INTERCAL. It's a wild and wacky language, somewhere between comedy and cutting satire. But the compiler was never circulated. There would be later implementations, but that original compiler remained lost to time. That is, until now. This episode covers how the original source code was found, and my attempt to get it up and running. Get the source code for INTERCAL72 here: https://github.com/rottytooth/INTERCAL72/ Read the original INTERCAL manual: https://3e8.org/pub/intercal.pdf

    Only S1 Users Will Survive!

    The S1 operating system can do it all! It can run on any computer, read any disk, and execute any software. It can be UNIX compatible, DOS compatible, and so, so much more! But... can S1 ship? Today we are talking about an operating system that sounds too good to be true. Is it another example of vaporware? Or is S1 really the world's most sophisticated operating system?

    RPG, a Different Paradigm?

    How do you make a computer act less like a computer? It sounds like some kind of riddle, but in the early 1960s it was an actual problem. As IBM customers transitioned from tabulators to computers they ran into all sorts of practical issues. Programmers became a hot commodity. But how do you find a programmer in 1959? And how can you even afford such a luxury? Wouldn't it be better if you could just use your new computer as a tabulator? Well, with RPG, all that and more was possible.

    LINC

    In the early 1960s a neat little machine came out of MIT. Well, kind of MIT. The machine was called LINC. It was small, flexible, and designed to live in laboratories. Some have called it the first personal computer. But, is that true? Does it have some secret that will unseat my beloved LGP-30? And how does DEC fit into the picture?

    ACTing Up

    The LGP-30 is one of my favorite computers. It's small, scrappy, strange, and wonderous. Among its many wonders are two obscure languages: ACT-I and ACT-III. In this episode we are exploring the ACTS, how the LGP-30 was programmed in practice, and why I've been losing sleep for the last few weeks.
