Episode 178 - The Programma 101

Advent of Computing ·

2026/03/22

The Olivetti Programma 101 isn't quite like any other machine. On first glance it looks like a big desktop calculator. Inside, it's a purebred computer... but strange one. It uses twisted spring steel for memory, has no addresses, and it's machine code looks more like a spell than a program. It's existence is due, in no small part, to a man being very mean to GE engineers. Like Advent of Computing? Then check out the after show!

Episode 177 - Getting Real with RSX

Advent of Computing ·

2026/02/23

Who wants to hear me make incorrect assumptions about old software? RSX is a system that, from the outside, can sound like it has a similar story to that of UNIX. First developed for the PDP-15 in 1969, RSX becomes much more well known when it migrates to the PDP-11. It becomes a multitasking and multiuser system. A key difference is niche. While UNIX is a very general purpose system RSX is built for real time. That leads to something very unique.

Episode 176 - Is That Even UNIX?

Advent of Computing ·

2026/02/09

UNIX is beloved by many. It's the classic minicomputer operating system. It's big, it's powerful, it's multitasking, and it has some very specific memory requirements. So what happens when you try and get UNIX to run on a microcomputer? Hilarity ensues. Today we are looking at 3 small versions of UNIX: OMNIX, LSX, and CROMIX. And, I'll tell you, one of these is closer to vaporware than the others.

Episode 175 - SNOBOL? That's Disgusting!

Advent of Computing ·

2026/01/28

Today we are talking about one of the most unique languages I've ever come across. SNOBOL emerges from the early days of programming. It's first compiler is implemented on the back of an envelope. It only has one data type, and only one format for every line of code. It's the bane of Chester, and center of an office drama! What's not to love?

Episode 174 - The Bell Model I

Advent of Computing ·

2026/01/12

We are getting back to the actual digital family tree. In 1937 George Stibitz built a tiny binary adding circuit on his kitchen table using scraps he "liberated" from his job at Bell Labs. In 1940 he demonstrated a machine he called a computer. That research forms one of the foundations of modern computing. It also forms a weird temporal phenomenon that I have yet to name. Maybe the Curse of '37? Selected Sources: Zeroth Generation by George Stibitz (NOW WITH A 2nd EDITION!)

Episode 173 - Hybrid Programming

Advent of Computing ·

2025/12/29

Hybrid computers are composed of a digital computer linked to an analog computer. That leads to an interesting challenge: how do you write software for one of these things? The analog side actively resists programming, while the digital side can't comprehend of continuous values. In the 1960s specialized languages appeared that tried to bridge this divide. And, I assure you, they are not at all like what you would expect.

Episode 172 - Analog/Hybrid

Advent of Computing ·

2025/12/15

In 1945 the first electronic digital computers sparked to life. Number crunching was instantly changed forever! The perfect technology had arrived, and there was never even a competition, right? Well, not so much. The simple fact is that computers sucked for decades. Digital machines have all kinds of inherent pitfalls. There was another entire lineage of computers that existed in the shadow of digital machines: the analogs. Eventually the two technologies would merge in an attempt to create

Episode 171 - What Is a 4GL?

Advent of Computing ·

2025/11/24

Last episode I said that Fourth Generation Languages were a topic for another time. Well... this counts as another time. Today we are trying to figure out what exactly makes a language 4th Generation. Along the way we will see why the term bugs me so much, why 4GLs seem so strange, and how a programmer can increase their productivity by 2,000% (some restrictions apply).

I'm back to normal episodes, and I'm running out the gate with a weird one. Thoroughbred/OS was a multi-user and multi-tasking operating system for the IBM PC. It's mian interface was... BASIC of all things! What exactly is this oddity? https://winworldpc.com/product/thoroughbred-os/662 - Try Out Thoroughbred/OS yourself

Episode 169.5 - Ben Zotto and the Story of Sphere...

Advent of Computing ·

2025/11/01

I recently had the chance to talk to Ben Zotto about his upcoming book: Go Computer Now! - The Story of Sphere Computers. It's all about an obscure machine powered by the Motorola 6800 that released in 1975. I figured it was the perfect faire for my audience. And... I really want to read this book!

Episode 169 - Dellinger's Viruses

Advent of Computing ·

2025/10/26

In 1981 Joe Dellinger attempted to create the perfect computer program: a virus that spread silently. In 1982 a revision of that virus broke containment. It would have remained completely hidden if it wasn't for an obscure Apple II game. Today we look at the story and motivation behind that virus, and how it slipped into the sands of time. Or... did it!? The truth is if you have an Apple II it may be infected with Dellinger's virus! My main source:

Episode 168 - Halt and Catch Fire

Advent of Computing ·

2025/10/19

Imagine a secret number that could be used to bring your computer to a screeching halt. In 1977 Gerry Wheeler discovered an interesting feature of Motorola's new 6800 microprocessor. There was a secret instruction that, if read, would cause the processor to stop working. He called this magic number Halt and Catch Fire, or HCF, and wrote a neat article about the operation. This was the first time the public would learn about the secret powers of HCF, but this isn't actually the beginning of

Episode 167 - The Tape That Unwound Itself

Advent of Computing ·

2025/10/12

Have you ever had a computer do something you can't explain? Have you ever thought a machine had a mind of its own? In 1971 Met Life was faced with this exact conundrum. Their tape drives, for some reason, were throwing tape all over the floor every night. Systems were checked and no flaws were found, but every morning an operator would walk in on an absolute mess. What could make a healthy machine spit up it's precious tape?

Episode 166 - Beyond the PDP-11

Advent of Computing ·

2025/10/05

My trilogy on the PDP-11 concludes with a look at the far flung places this computer can take us. In this episode we look at some issues with claims of the PDP-11's linage, smuggling, Hungarian-made microcode, and much more. Along the way we answer the question: if the PDP-11 was such a good design then where was it during the home computing boom of the 80s?

Episode 163 - Ever Heard of the PDP-11?

Advent of Computing ·

2025/08/24

The DEC PDP-11 is one of the most influential minicomputers of all time. Some would even call it the most influential computer of all time. But where exactly did it come from? How was it designed? This episode is the start of a 3 part series that will look at how the PDP-11 was created, adapted to changes, and the strange places it ended up.

Episode 162 - CSIRAC, Australia's First Computer

Advent of Computing ·

2025/08/10

In 1949 CSIRAC sprung to life in a lab in Sydney, Australia. It was a very early stored program computer. All machines of the era were unique. But CSIRAC, well, it was very unique indeed.

Episode 161 - The IAS Machine

Advent of Computing ·

2025/07/13

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? The Eastern
