How Sony Mastered The Transistor

September 4, 2024 by Al Williams 35 Comments

When you think of Sony, you probably think of a technology company that’s been around forever. However, as [Asianometry] points out, it really formed in the tough years after World War II. The two people behind the company’s formation were an interesting pair. One of them was a visionary engineer and one was a consummate businessman.

While it is hard to imagine today, securing a license to produce transistors was difficult in the early days. What’s worse is, even with the license, it was not feasible to use the crude devices in a radio.

The Famous Computer Cafe Has Now Been Archived Online

August 23, 2024 by Lewin Day 4 Comments

You might think that TV stations or production houses would be great at archiving, but it’s not always the case. Particularly from the public access perspective. However, if you’re a fan of The Famous Computer Cafe, you’re in luck! The beloved series has now been preserved on The Internet Archive!

If you’re not familiar with the show, it was a radio program broadcast from 1983 to 1986. It was pumped out of a variety of radio stations in southern and central California in the period. The creators making sure to keep a copy of each episode in reel-to-reel tape format. For years, these tapes were tragically lost, until archivist [Kay Savetz] was able to recover some of them from a recent property sale. From there, a GoFundMe paid for digitization, and the show has been placed on The Internet Archive with the blessings of the original creators.

This is quite the cultural victory, particularly when you observe the list of guests on the show. Timothy Leary, Bill Gates, Jack Tramiel, and even Douglas Adams made appearances in the recovered recordings. Sadly, though, not all the tapes have been recovered. Episodes with Gene Roddenberry, Robert Moog, and Ray Bradbury are still lost to time.

If you fancy a listen, 53 episodes presently exist on the archive. Take a trip back in time and hear from some technological visionaries—and futurists—speaking their minds at the very beginning of the microcomputer era! If you find any particularly salient gems, don’t hesitate to drop them on the tip line.

A Brief History Of AlphaSmart

July 29, 2024 by Navarre Bartz 18 Comments

There are a handful of gadgets that do one thing so well that they become cult classics long after the company that made them has moved on or closed up shop. [This Does Not Compute] takes us through the history of the AlphaSmart word processor which started as an educational tool, but finds itself in many a writer’s bag today.

The original AlphaSmart bears more than a passing resemblance to its Apple contemporaries since the company was founded by two Apple engineers. The Cupertino company didn’t see the value in the concept, but didn’t lean on any non-competes to keep the pair from pursuing the idea on their own time either. What resulted was a dead simple word processor that could be had for 1/5 of what a new computer typically cost in the era, which was particularly attractive for the target market of schools.

After several successful years, the pressure of PDAs and then smartphones from one side and cheaper laptops from the other meant school districts no longer wanted single-purpose devices when they could have a fully-fledged computing experience for students. We wonder if that was the right call, with so many now wanting distraction-free devices, but it was the end of the road for the company either way.

Our own [Kristina Panos] and [Tom Nardi] have shown us the guts of the Neo and of one of its competitors, the Writer, respectively. If you have a Neo of your own in need of replacement keycaps, you can print them.

Dad? Where Did Printed Circuit Boards Come From?

July 5, 2024 by Al Williams 18 Comments

These days, it is hard to imagine electronics without printed circuit boards. They are literally in everything. While making PCBs at home used to be a chore, these days, you design on a computer, click a button, and they show up in the mail. But if you go back far enough, there were no PC boards. Where did they come from? That’s the question posed by [Steven Leibson] who did some investigating into the topic.

There were many false starts at building things like PCBs using wires glued to substrates or conductive inks. However, it wasn’t until World War II that mass production of PC boards became common. In particular, they were the perfect solution for proximity fuzes in artillery shells.

The SS United States: The Most Important Ocean Liner We May Soon Lose Forever

June 27, 2024 by Maya Posch 14 Comments

Although it’s often said that the era of ocean liners came to an end by the 1950s with the rise of commercial aviation, reality isn’t quite that clear-cut. Coming out of the troubled 1940s arose a new kind of ocean liner, one using cutting-edge materials and propulsion, with hybrid civil and military use as the default, leading to a range of fascinating design decisions. This was the context in which the SS United States was born, with the beating heart of the US’ fastest battle ships, with light-weight aluminium structures and survivability built into every single aspect of its design.

Outpacing the super-fast Iowa-class battleships with whom it shares a lot of DNA due to its lack of heavy armor and triple 16″ turrets, it easily became the fastest ocean liner, setting speed records that took decades to be beaten by other ocean-going vessels, though no ocean liner ever truly did beat it on speed or comfort. Tricked out in the most tasteful non-flammable 1950s art and decorations imaginable, it would still be the fastest and most comfortable way to cross the Atlantic today. Unfortunately ocean liners are no longer considered a way to travel in this era of commercial aviation, leading to the SS United States and kin finding themselves either scrapped, or stuck in limbo.

In the case of the SS United States, so far it has managed to escape the cutting torch, but while in limbo many of its fittings were sold off at auction, and the conservation group which is in possession of the ship is desperately looking for a way to fund the restoration. Most recently, the owner of the pier where the ship is moored in Philadelphia got the ship’s eviction approved by a judge, leading to very tough choices to be made by September.

Institutional Memory, On Paper

May 11, 2024 by Elliot Williams 18 Comments

Our own Dan Maloney has been on a Voyager kick for the past couple of years. Voyager, the space probe. As a long-term project, he has been trying to figure out the computer systems on board. He got far enough to write up a great overview piece, and it’s a pretty good summary of what we know these days. But along the way, he stumbled on a couple old documents that would answer a lot of questions.

Dan asked JPL if they had them, and the answer was “no”. Oddly enough, the very people who are involved in the epic save a couple weeks ago would also like a copy. So when Dan tracked the document down to a paper-only collection at Wichita State University, he thought he had won, but the whole box is stashed away as the library undergoes construction.

That box, and a couple of its neighbors, appear to have a treasure trove of documentation about the Voyagers, and it may even be one-of-a-kind. So in the comments, a number of people have volunteered to help the effort, but I think we’re all just going to have to wait until the library is open for business again. In this age of everything-online, everything-scanned-in, it’s amazing to believe that documents about the world’s furthest-flown space probe wouldn’t be available, but so it is!

It makes you wonder how many other similar documents – products of serious work by the people responsible for designing the systems and machines that shaped our world – are out there in the dark somewhere. History can’t capture everything, and it’s down to our collective good judgement in the end. So if you find yourself in a position to shed light on, or scan, such old papers, please do! And then contact some nerd institution like the Internet Archive or the Computer History Museum.

Retrogadgets: Butler In A Box

March 28, 2024 by Al Williams 11 Comments

You walk into your house and issue a voice command to bring up the lights and start a cup of coffee. No big deal, right? Siri, Google, and Alexa can do all that. Did we mention it is 1985? And, apparently, you were one of the people who put out about $1,500 for a Mastervoice “Butler in a Box,” the subject of a Popular Science video you can see below.

If you think the box is interesting, the inventor’s story is even stranger. [Kevin] got a mint-condition Butler in a Box from eBay. How did it work, given in 1983, there was no AI voice recognition and public Internet? We did note that the “appliance module” was a standard X10 interface.
