Inside a DEC Hard Drive
A lot of technology from the not-so-distant past doesn’t resemble modern versions very much. For a case in point, look at the DEC RS08 disk drive meant to pair with …read more Continue reading Inside a DEC Hard Drive

Reproduction 1960s Computer Trainer Really Pushes Our Buttons
If you were selling computers in the early 1960s you faced a few problems, chief among them was convincing people to buy the fantastically expensive machines. But you also needed to develop an engineering force to build and maintain said machines. And in a world where most of the electrical …read more

An Entire PDP-11 On Your Bench
The DEC PDP series of minicomputers occupy a special place in computing history for us, because as the workhorses of commercial computing from the 1960s through to some time in the 1990s they provided the bedrock upon which so many of the computing technologies we take for granted today were …read more
Getting Started with Blinking Lights on Old Iron
If you ever go to a computer history museum, you’ll be struck by how bland most modern computers look. Prior to 1980 computers had lights and switches, and sometimes dials and meters. Some had switchboard-like wiring panels and some even had oscilloscope-like displays. There’s something about a machine with all those switches and lights and displays that gets your hacker juices flowing. Have you ever wanted to get started in retrocomputing? Is it difficult? Do you need a lot of money? That depends on what your goals are.
There are at least three ways you can go about participating in …read more

The PDP-1: The Machine that Started Hacker Culture
One of my bucket list destinations is the Computer History Museum in Mountain View, California — I know, I aim high. I’d be chagrined to realize that my life has spanned a fair fraction of the Information Age, but I think I’d get a kick out of seeing the old machines, some of which I’ve actually laid hands on. But the machines I’d most like to see are the ones that predate me, and the ones that contributed to the birth of the hacker culture in which I and a lot of Hackaday regulars came of age.
If you were …read more

A Modern Day PDP-11 Front End
Hands up if you feel your spiritual home is in front of a terminal with a “DIGITAL” logo on it. It’s a name that has long ago been subsumed into first Compaq and then by extension HP, but it’s one with a lot of history when it comes to computing.
From the start of the electronic computing age, there were the computers we’d probably now describe as mainframes. Big computers that cost the GDP of a small country, filled an entire floor of a building, and could only be found in government departments, universities, and large companies. By the 1960s, …read more
Hackaday Links: January 8, 2017
What do you get when mindless automatons with no capacity for reason or logic converse? While you discuss that in the comments, here are two chatbots on Twitch. The highlights? A few hours ago they were doing the cutesy couple, “‘I love you more!’, ‘No, I love you more!’” thing. This was ended by, “Error, cannot connect to server.” Even robot love is not eternal.
3D printer nozzles wear out. Put a few hundred hours on a brass nozzle, and you’re not going to get the same print quality as when you started. This has led to stainless and silly-con …read more

A PDP-11 On A Chip
If you entered the world of professional computing sometime in the 1960s or 1970s there is a high probability that you would have found yourself working on a minicomputer. These were a class of computer smaller than the colossal mainframes of the day, with a price tag that put them within the range of medium-sized companies and institutions rather than large corporations or government-funded entities. Physically they were not small machines, but compared to the mainframes they did not require a special building to house them, or a high-power electrical supply.
One of the most prominent among the suppliers of …read more
Hackaday Prize Entry: Autorouters Are For The Weak
[Yann]’s DYPLED entry into this year’s Hackaday Prize isn’t very useful to most people. It’s a tiny module that connects to a 16-bit parallel bus, and displays a hexadecimal number on a few LEDs. It’s useful if you’re diagnosing a problem on a computer from 1982, but just barely. The real wonder here is how [Yann] is doing this cheaply and easily using some weird techniques and strange parts.
The display for this tiny device is an array of 36 LEDs, arranged into a set of five seven-segment displays. Homebrew seven-segment displays are cool, but how is he driving it? …read more
