Atari Introduces A New Old Console

September 11, 2023 by Tom Nardi 29 Comments

Readers of a certain age no doubt remember the Atari 2600 — released in 1977, the 8-bit system helped establish the ground rules for gaming consoles as we know them today, all while sporting a swanky faux wood front panel designed to make the system look at home in contemporary living rooms.

Now, nearly 50 years later, the Atari 2600 is back. The new system, imaginatively named the 2600+, looks exactly like the original system, albeit at around 80% scale. It will also work the same way, as the system will actually be able to play original Atari 2600 and 7800 cartridges. This is something of a surprise when compared to the previously released retro consoles from the likes of Sony and Nintendo, as they were all limited to whatever games the company decided to pack into them. Of course, this probably has something to do with the fact that Atari has been selling newly manufactured 2600 games for some time now.

Although it will play original cartridges, it’s still an emulated console at heart. There aren’t a lot of technical details on the product page, but it does say the 2600+ is powered by a Rockchip 3128 SoC with 256 MB of DDR3 RAM and 256 MB eMMC flash. Some quick searching shows this to be a pretty common board for set-top gadgets, and wildly overpowered considering the meager requirements for emulating a game console from 1977. We wouldn’t be surprised to find it’s running some kind of minimal Linux install and using one of the existing open source emulators.

While the 2600+ sports the same 9-pin D-sub controller connectors as the original console, it thankfully embraces modern display technology and outputs over HDMI. Each console will come with a “10-in-1” cartridge that contains some of the console’s most popular titles, as well as a modernized version of the original single-button joystick. (Unlike the original, the 2600+ comes with only a single joystick — the other is sold separately.)

Atari won’t start shipping the 2600+ until this fall, but they’re currently taking preorders for the $130 system. We’re eager to see somebody pull it apart, as the earlier “mini” consoles ended up being ripe for hacking.

Restoring A 45 Year Old Video Game

August 30, 2023 by Julian Scheffers 28 Comments

When we say vintage video game, some of you may think of the likes of Lemmings, Mario or maybe even Donkey Kong but the game that [Vintage Apparatus] restored is slightly older and much more minimalist, using an LED matrix and some 7-segment displays rather than this newfangled color CRT thing.

The front and back covers, buttons and screws of the game on the workbench. — The game is disassembled before cleaning.

[Vintage Apparatus] starts by removing the battery and cover from the 1977 Mattel electronics (American) football game, which uses rather uncommon 2mm triangular screws. To his and our surprise, the circuit board and its beautiful array of LEDs seem to be in excellent condition, so he moves on to cleaning the case itself.

The case, on the other hand, is a bit dirty on the outside, so [Vintage Apparatus] takes out the buttons and starts cleaning with the back cover a Q-tip. After a bit of scrubbing and some extra care to avoid removing any stickers, he moves on to the considerably dirtier and somewhat scratched front case. After some wrestling with the creases and speaker grill of the front cover, the outside of the front case looks nice and clean. Finally, he puts back the buttons and circuit board in the front cover before adding closing it all up with the back cover and screwing it back together.

The game, which immediately comes to life and was actually made by the Mattel calculator division, is a sort of evasion game where the player is a bright dot that can move forward, up or down. The player avoids the dimmer dots, the “tacklers”, in order to run as far as possible as fast as possible. When one of the tacklers tackles the player, the amount of downs is increased and the fifth down means game over. After either scoring or getting downed one too many times, the field is flipped and it’s now player 2’s turn.

Video after the break.

Turning Soviet Electronics Into A Nixie Tube Clock

August 27, 2023 by Donald Papp 17 Comments

Sometimes you find something that looks really cool but doesn’t work, but that’s an opportunity to give it a new life. That was the case when [Davis DeWitt] got his hands on a weird Soviet-era box with four original Nixie tubes inside. He tears the unit down, shows off the engineering that went into it and explains what it took to give the unit a new life as a clock.

Each digit is housed inside a pluggable unit. If a digit failed, a technician could simply swap it out.

A lot can happen over decades of neglect. That was clear when [Davis] discovered every single bolt had seized in place and had to be carefully drilled out. But Nixie tubes don’t really go bad, so he was hopeful that the process would pay off.

The unit is a modular display of some kind, clearly meant to plug into a larger assembly. Inside the unit, each digit is housed in its own modular plug with a single Nixie tube at the front, a small neon bulb for a decimal point, and a bunch of internal electronics. Bringing up the rear is a card edge connector.

Continues after the break…

A Mainframe Computer For The Modern Age

August 21, 2023 by Bryan Cockfield 50 Comments

The era of mainframe computers and directly programming machines with switches is long past, but plenty of us look back on that era with a certain nostalgia. Getting that close to the hardware and knowing precisely what’s going on is becoming a little bit of a lost art. That’s why [Phil] took it upon himself to build this homage to the mainframe computer of the 70s, which all but disappeared when PCs and microcontrollers took over the scene decades ago.

The machine, known as PlasMa, is not a recreation of any specific computer but instead looks to recreate the feel of computers of this era in a more manageable size. [Phil] built the entire machine from scratch, and it can be programmed directly using toggle switches to input values into registers and memory. Programs can be run or single-stepped, and breakpoints can be set for debugging. The internal workings of the machine, including the program counter, instruction register, accumulator, and work registers, are visible in binary lights. Front panel switches let you control those same items.

The computer also hosts three different microcodes, each providing a unique instruction set. Two are based on computers from Princeton, Toy-A, and Toy-B, used as teaching tools. The third is a more advanced instruction set that allows using things like emulated peripherals, including storage devices. If you want to build one or just follow along as the machine is constructed, programmed, and used, [Phil] has a series of videos demonstrating its functionality, and he’s made everything open-source for those more curious. It’s a great way to get a grasp on the fundamentals of computing, and the only way we could think of to get even more into the inner workings of a machine like this is to build something like a relay computer.

Recreating The Golden Era Of Cable TV

July 13, 2023 by Bryan Cockfield 55 Comments

Fewer and fewer people have cable TV subscriptions these days, due to a combination of poor business practices by cable companies and the availability of alternatives to cable such as various streaming platforms. But before the rise of the Internet that enabled these alternatives, there was a short period of time where there were higher-quality channels, not too many commercials, a possibly rose-tinted sense of wonder, and where MTV actually played music. [Irish Craic Party] created this vintage cable TV network to capture this era of television history.

The hardware for this build is a Raspberry Pi driving an LCD display recovered from an old iPad. There’s a custom TV tuner which handles changing the channels and interfaces with an Apple Remote. Audio is sent through old computer speakers, and the case is built from 3D printed parts and some leftover walnut plywood to give it an era-appropriate 80s or early 90s feel. We’ve seen other builds like this before, but where this one really sets itself apart is in the software that handles the (television) programming.

[Irish Craic Party] has gone to great lengths here to recreate the feel of cable TV from decades ago. It has recreations of real channels like HBO, Nickelodeon, and FX including station-appropriate bumpers and commercials. It’s also synchronized to the clock so shows start on the half- or quarter-hour. Cartoons play on Saturday morning, and Nickelodeon switches to Nick-at-Nite in the evenings. There are even channels that switch to playing Christmas movies at the appropriate times, complete with Christmas-themed commercials.

The build even hosts a preview channel, one of the more challenging parts of the build. It continually scrolls through the channels and shows what’s currently playing and what will be showing shortly, complete with a commercial block at the top. For those who were around in the 90s it’s almost a perfect recreation of the experience of watching TV back then. It can even switch to a video game input when tuned to channel 3. There’s almost too much to go into in a short write-up so be sure to check the video after the break.

Thanks to [PCrozier] for the tip!

Computer Speed Gains Erased By Modern Software

July 2, 2023 by Bryan Cockfield 284 Comments

[Julio] has an older computer sitting on a desk, and recorded a quick video with it showing how fast this computer can do seemingly simple things, like open default Windows applications including the command prompt and Notepad. Compared to his modern laptop, which seems to struggle with even these basic tasks despite its impressive modern hardware, the antique machine seems like a speed demon. His videos set off a huge debate about why it seems that modern personal computers often appear slower than machines of the past.

After going through plenty of plausible scenarios for what is causing the slowdown, [Julio] seems to settle on a nuanced point regarding abstraction. Plenty of application developers are attempting to minimize the amount of development time for their programs while maximizing the number of platforms they run on, which often involves using a compatibility layer, which abstracts the software away from the hardware and increases the overhead needed to run programs. Things like this are possible thanks to the amount of computing power of modern machines, but not without a slight cost of higher latency. For applications developed natively, the response times would be expected to be quite good, but fewer applications are developed natively now including things that might seem like they otherwise would be. Notepad, for example, is now based on UWP.

While there are plenty of plausible reasons for these slowdowns in apparent speed, it’s likely a combination of many things; death by a thousand cuts. Desktop applications built with a browser compatibility layer, software companies who are reducing their own costs by perhaps not abiding by best programming practices or simply taking advantage of modern computing power to reduce their costs, and of course the fact that modern software often needs more hardware resources to run safely and securely than equivalents from the past.

Retro-Inspired Computer Case Hosts Mechanical Keyboard

June 24, 2023 by Bryan Cockfield 5 Comments

During the time in the 1980s when the personal computer was gaining steam as a household fixture, plenty of models shipped with the keyboard built in to the machine itself. This helped reduce costs, lower the physical footprint of the device, and arguably improved aesthetics. But as technology progressed, this type of design fell by the wayside as computers became more modular and configurable. That’s not to say there aren’t any benefits to building a computer like this, though. [jit] is here to show off this Amiga-inspired computer with its own modern built-in mechanical keyboard.

Like the Raspberry Pi 400 which is built into its own case, modern computers like this are extremely portable, relatively simple, and space-efficient. But [jit] did not like the uninspired design of the Pi so he was looking to make some improvements. Starting with the keyboard, it boasts a 60% size board with mechanical keys which are backlit by LEDs. Inside the machine is a Odroid XU4 which has a little bit more power (and is often easier to find) than a comparable Raspberry Pi. The case is 3D printed and includes ventilation and support for the addition of various cooling fans, I/O ports, status LEDs, and switches for the computer inside.

Additionally, some modification of the Odroid itself was needed in order to move the various switches to the case, and the build also includes a somewhat customized power supply internally as well. It’s a well-rounded build that captures the spirit of the old computer cases, but takes advantage of a lot of modern technology at the same time. If you want to go all-out with a build like this, though, take a look at this retro-inspired case (with keyboard included) that manages to get most of a Framework laptop inside.
