Episode 36 - The Rise of CP/M

Advent of Computing ·

2020/08/09

The IBM PC and MS-DOS, the iconic duo of the early 80s. The two are so interconnected that it's hard to mention one without the other. But in 1980 DOS wasn't IBM's first choice for their soon-to-be flagship hardware. IBM had wanted to license Gary Kildall's CP/M, but in a strange series of events the deal fell through. Legend states that Kildall lost the contract b was too busy flying his private plane to talk business with IBM, but is that true? Today we look at the development of CP/M, why it was

2020/07/26

A lot of the technology we associate with the modern day started on anachronistic machines. I'm not talking about mainframes, I'm talking older. Today we are looking at George Julius's Automatic Totalisator, an analog computer used to manage betting at horse tracks around the world. These were massively complex machines, some networked over 200 input terminals, and they did it all mechanically. Like the show? Then why not head over and support me on Patreon.

Episode 34 - 8080 VS Z80

Advent of Computing ·

2020/07/12

In 1974 Intel released the 8080 processor, a chip long in the making. It was the first microprocessor that had the right combination of power and price to make personal computers viable. But that same year a small group of employees defected and formed their own company called Zilog. Among this group were Masatoshi Shima and Federico Faggin, two of the principal architects behind the 8080 as well as Intel's other processors. Zilog would go on to release a better chip, the Z80, that blew Intel out of

I recently got the chance to sit down and talk with Microsoft alumni Brad Chase. He was the product manager for Microsoft Works on the Macintosh, DOS 5, DOS 6, and the marketing lead for Windows 95 as well as much more. We talk about the Apple-Microsoft relationship, the groundbreaking launch of Windows 95, and what it takes to sell software.

Episode 33 - Becoming Portable

Advent of Computing ·

2020/06/28

Portable computing is now totally ubiquitous. There's a good chance you are listening to this episode on a tiny portable computer right now. But where did it all come from? As it turns out the first portable computer was designed all the way back in 1972. This machine, the DynaBook, only ever existed on paper. Despite that handicap, in the coming years it would inspire a huge shift in both personal and portable computing. Like the show? Then why not head over and support me on Patreon. Perks include

Episode 32 - Road to Transistors, Part II

Advent of Computing ·

2020/06/14

In this episode we finish up our look at the birth of the transistor. But to do that we have to go back to 1880, the crystal radio detector, and examine the development of semiconductor devices. Once created the transistor would change not just how computers worked, but change how they could be used. That change didn't happen over night, and it would take even longer for the transistor to move from theory to reality. Like the show? Then why not head over and support me on Patreon. Perks include

Episode 31 - Road to Transistors: Part I

Advent of Computing ·

2020/05/31

The transistor changed the world. It made small, complex, and cheap computing possible. But it wasn't the first attempt to crack the case. There is a long and strange lineage of similar devices leading up to the transistor. In this episode we take a look at two of those devices. First the vacuum tube, one of the first components that made computing possible. Then the cryotron, the first device purpose built for computers.

Episode 30 - Coherent Is Not UNIX!

Advent of Computing ·

2020/05/17

In the current day Linux is the most widely used UNIX-like operating system. It's rise to prominence has been an amazing success story. From it's humble beginnings Linux has grown to power everything from super computers to car stereos. But it's not the first UNIX clone. A much earlier system existed, called Coherent. And as it turns out both Linux and Coherent share a lot of similarities. The biggest difference being that Coherent was closed source. Like the show? Then why not head over and support

Episode 29.5 - A Guided Tour of the Macintosh

Advent of Computing ·

2020/05/10

In this byte sized episode I take a look at a pack in that came with the first Macintosh. Along side Apple stickers, manuals, and the computer itself there was a single cassette tape labeled "A Guided Tour of the Macintosh". The purpose? It's a strange addition to the Mac's packing, but a great example of Apple's attention to detail and ingenuity. Like the show? Then why not head over and support me on Patreon.

Episode 29 - PCM, Origins of Digital Audio

Advent of Computing ·

2020/05/03

Every day we are inundated with digital audio: phone calls, music, even this podcast. Digitized sound has become so ubiquitous that it often fades into the background. What makes this all possible is a technology called Pulse Code Modulation, or PCM. This isn't new technology, its roots trace all the way back to 1937. So how exactly did digital audio come into being well before the first digital computers? Like the show? Then why not head over and support me on Patreon. Perks include early access to

Advent of Computing ·

2020/04/19

It's easy to think of Apple and Microsoft as bitter rivals, but that's not always the case. The two companies have a very complicated relationship, and a very long history. This connection goes all the way back to the 1970s and a product called Applesoft BASIC. It would become stock software on nearly every Apple II computer ever sold, it kept Apple competitive in the early home computer market, and it may have saved Microsoft from bankruptcy.

Episode 27 - Vectrex, Playing With Vectors

Advent of Computing ·

2020/04/05

The 1980s were a turbulent and fast-moving decade for the video game industry. There were huge success stories, rapid advancements in technology, and the North American Video Game Crash. Caught up in all of this was an ambitious machine called the Vectrex. In an era dominated by pixelated graphics the Vectrex brought higher resolution vector images and early 3D to market. But ultimately it would be swept away during the market's crash. Today we are taking a dive into the development of the Vectrex,

2020/03/22

The widespread use of the internet has shaped our world, it's hard do imagine the modern day without it. One of the biggest featured would have to be the hyperlink. But despite the modern net feeling so new, links actually date back as far as the 1930s and the creation of the Memex: a machine that was never built but would influence coming generations of dreamers.

Episode 25 - Making Disks Flexible, Part 2

Advent of Computing ·

2020/03/08

The floppy disk is one of the most iconic pieces of technology. While not in use in the modern day there was a period of 40 years where the floppy disk was synonymous with data storage. Today we pick up where we finished in the last episode, with the rise and fall of the 5 1/4 inch disk. We will be looking at the creation and spread of the 3 1/2 inch floppy disk. How did Sony, a non-player in the computer market, create this run away success? And how did Apple contribute to it's rise? Like the show

The floppy disk was a ubiquitous technology for nearly 40 years. From mainframes to home computers, the plastic disk was everywhere. And in the decades it was around there were very few changes made to how it fundamentally worked. So how did it get so popular? What made the floppy disk so flexible? And how did it finally fall out of favor? In this episode we will look at the technology's early days. Like the show? Then why not head over and support me on Patreon.

Advent of Computing ·

2020/02/10

Our modern world is full of software, it's what makes everything tick. The sheer amount of code that goes into something like keeping the internet running is staggering. Programming isn't the easiest profession, but there was a time when it was much much harder. It took a huge shift in thinking, and some impressive feats of software development, to make complicated programming possible. And that shift started in the 1950s. Like the show?

2020/01/26

Many video games today make use of randomized content, some more than others. It may seem like an obvious feature, but it turns out that procedural generation didn't really catch on in video games until the 1980 release of Rogue. The game itself never saw much commercial success, but was wildly popular among UNIX users. In this episode we look at Rogue, how it was created, and the legacy that we still see today.

This episode we will be looking at the 8008, the second microprocessor produced by Intel and the progenitor of the x86 family.
