Sega Meganet: Online Gaming In 1990

Published

on

It’s easy to think of online console gaming as an invention of the 2000s. Microsoft made waves when Xbox Live dropped in 2002, with Nintendo and Sony scrambling to catch up with their own offerings that were neither as sleek or well-integrated.

However, if you were around a decade earlier, you might have experienced online console gaming much closer to the dawn of the Internet era. As far back as 1990, you could jump online with your Sega Mega Drive. But what did an online console feel like in the dial-up era?

Mega

The Sega Mega Drive was launched in Japan in October 1988. The company was in a tough battle with Nintendo for gaming dominance, and the new 16-bit console was intended to best its rival’s offerings across the board. With a forward-looking attitude, Sega quickly developed an online offering for the console, which went under a few different names. It was known as Mega Net, or alternatively, the Sega Net Work System.

The system hit the market on November 3 1990, exclusively for the Japanese market, with Sega talking up a future launch in the US under the “Tele-Genesis” name. The initial Mega Net kit cost ¥12,800, which included the Mega Modem accessory—a simple 1,200 bps dial-up modem which plugged into the “EXT” DE-9 port on the back of the Model 1 Mega Drive. Access to Mega Net service came at a cost of ¥800 a month. Users got a copy of Nikkan Sports Pro Baseball VAN, which provided live updates and statistics on baseball matches when connected to the service.

The Mega Net pack also included the “Game Library” cartridge. This allowed users to dial up to Mega Net and play a variety of downloadable games. These titles had to be incredibly compact, usually under 128 KB. This was both because of the glacially slow 1,200 bps modem, and because the Mega Drive had no real storage capability to speak of. 42 games were released on the system, and titles would take about 5 to 8 minutes to download. The vast majority were single player experiences. However, two games – Tel-Tel Stadium and Tel-Tel Mahjong – featured online play via Mega Net. Perhaps unsurprisingly, both games were turn-based—a practical necessity given the limited speeds and latency achievable with the slow Mega Modem. A handful of games from Mega Net would later see cartridge releases of their own.

Users could also engage in multiplayer gaming with certain cartridge-based titles. However, this was not using a server-based online system. Instead, this merely consisted of point-to-point dial-up play between two consoles equipped with the Mega Modem.

Mega Net wasn’t just limited to gaming, however. Sega explored more utilitarian uses for the Mega Drive with the release of Mega Anser. This came as a package that included the Mega Modem, the Mega Anser software, and a numeric keypad controller called the Ten Key Pad. There was also an optional printer that plugged into one of the controller ports. The most notable use of the Mega Anser was for online banking. Depending on your bank, you could manage your funds with the Naisu-kun Mini, Osaka Ginkou no Home Banking Service My Line, or Sumisei Home Tanmatsu.

Unfortunately, the technology wasn’t quite there in 1990 to support a fully-vibrant online gaming service. By 1992, Sega realised there wasn’t a large market for Mega Net and Mega Anser services, and the hardware started turning up in bargain bins for drastically reduced prices. By 1993, Sega had released a remodelled Mega Drive which eliminated the EXT port required for the Mega Modem, making it clear that there was no interest in taking the service any further.

The end of Mega Net in Japan was swift, but the name would live once more. That time came in 1995, when a similar service saw a last gasp release in Brazil, of all places. Supported by local distributor Tectoy, it ran using a unique modem accessory that plugged into the cartridge slot. The range of services on offer was quite different—users could access emails, fax messages, and read an electronic magazine called Revista Eletrônica. The system was designed to be used with the Sega Mouse for a more computer-like interface experience, and prices started at R$5 a month for access to the service. The service was, in many ways, completely unrelated to the original Sega effort, but was inspired by it and wore similar branding.

Brazil’s Mega Net was more modern and had additional ways for users to interact with each other.

Sega’s early experiment with online console gaming was not a grand success. It failed to attract a huge user base or offer any ground-breaking features. However, it did give the company a base to work from when it came to getting later consoles online, like the Saturn and Dreamcast that arrived years later. Ultimately, Sega would largely be out of the console market by the time online gaming really took off in that world, but you can’t fault the former Japanese titan for trying to get in early.

How a Protective Layer Gave Circuit Boards Their Signature Green Color

Published

on

Why PCB Circuit Boards are Green
Circuit boards are found in almost every electronic device that consumers use today. When you open your phone, computer, or a basic remote control, green is the first thing you notice. That famous green hue, however, does not come from the board material itself; it is due to a special coating known as solder mask, which covers the copper traces and gives them a green tint.



The solder mask is an essential tool for any board. After etching the copper paths onto the fiberglass basis, they apply a thin layer of polymer. The mask serves two important functions: it protects the copper from oxidation and moisture, which could cause harm, and it prevents solder from bridging between close connections while you’re assembling the item, which can result in short circuits. Without the mask, fragile circuitry could easily be damaged by regular handling or exposure to the environment.

Why PCB Circuit Boards are Green
Green became the go-to color all those years ago, when reliable solder masks first started rolling off the assembly line. The early ones used a combination of certain resins and hardeners that gave out a green tone, and it just so happened that there was an abundance of the green material available at the suppliers. So that became the industry norm. Over time, the industry has developed its entire process around this uniform green colour.

Why PCB Circuit Boards are Green
The human eye can tolerate green fairly well, especially when individuals stare at boards for hours on end under strong lighting. Green offers a fantastic contrast against the glossy copper pads and the white letters on top, reducing eye fatigue caused by staring at them for an extended period of time, since other hues have been found to be less durable. Automatic optical inspection equipment also operate better with green boards because their cameras and software have been tuned to work best with that color over time.

Why PCB Circuit Boards are Green
The cost of changing colors is also not high enough to make a significant difference. The green mask material requires less pigments in some formulations, making the production process easier because they don’t have to complicate the imaging and development procedures. The tighter design requirements associated with the conventional green color also provide them with more accurate control when exposed to ultraviolet radiation.

New Rowhammer attacks give complete control of machines running Nvidia GPUs

Published

on

So where do we go now?

The researchers said that both the RTX 3060 and RTX 6000 cards are vulnerable. Changing BIOS defaults to enable IOMMU closes the vulnerability, they said. Short for input-output memory management unit, IOMMU maps device-visible virtual addresses to physical addresses on the host memory. It can be used to make certain parts of memory off-limits.

“In the context of our attack, an IOMMU can simply restrict the GPU from accessing sensitive memory locations on the host,” Kwong explained. “IOMMU is, however, disabled by default in the BIOS to maximize compatibility and because enabling the IOMMU comes with a performance penalty due to the overhead of the address translations.”

A separate mitigation is to enable Error Correcting Codes (ECC) on the GPU, something Nvidia allows to be done using a command line. Like IOMMU, enabling ECC incurs some performance overhead because it reduces the overall amount of available workable memory. Further, some Rowhammer attacks can overcome ECC mitigations.

GPU users should understand that the only cards known to be vulnerable to Rowhammer are the RTX 3060 and RTX 6000 from the Ampere generation, which were introduced in 2020. It wouldn’t be surprising if newer generations of graphics cards from Nvidia and others are susceptible to the same types of attacks, but because the pace of academic research typically lags far behind the faster speed of product rollouts, there’s no way now to know.

Top-tier cloud platforms typically provide security levels that go well beyond those available by default on hobbyist and consumer machines. Another thing to remember: There are no known instances of Rowhammer attacks ever being actively used in the wild.

The true value of the research is to put GPU makers and users alike on notice that Rowhammer attacks on these platforms have the potential to upend security in serious ways. More information about GDDRHammer and GeForge is available here.

The iPhone Fold will allegedly feature a 3D-printed hinge.

With Apple’s first foldable expected to debut in late 2026, we’re now seeing more and more claims about its hardware. Following multiple rumors suggesting Liquid Metal would be used for the hinge of the iPhone Fold, another tipster has provided a new tidbit about the component.
To be more specific, a translated post from leaker Fixed Focus Digital on Weibo said that Apple is putting considerable effort into its foldable iPhone. This reportedly “involves chip-level high-molecular 3D printing technology, with further developments in the hinge design still to be revealed.”

IBM Teams Up With Arm To Run Arm Workloads On IBM Z Mainframes

Published

on

IBM and Arm are teaming up to let Arm-based software run on IBM Z mainframes. Network World reports: The two companies plan to work on three things: building virtualization tools so Arm software can run on IBM platforms; making sure Arm applications meet the security and data residency rules that regulated industries must follow; and creating common technology layers so enterprises have more software options across both platforms, IBM said in a statement.

IBM has not said whether the virtualization work will happen at the hypervisor level, through its existing PR/SM partitioning technology, or via containers — a question enterprise architects will need answered before they can assess the collaboration’s practical value. IBM described the effort as serving enterprises that run regulated workloads and cannot simply move them to the cloud, the statement said. IBM mainframe customers have largely missed out on the efficiency and price-performance gains Arm has already delivered in the cloud. “Arm says close to half of all compute shipped to top hyperscalers in 2025 runs on Arm chips, with AWS, Google, and Microsoft deploying their own Arm silicon through Graviton, Axion, and Cobalt, respectively,” reports Network World.

That gap is precisely what IBM and Arm’s collaboration intends to address. “This is a mainframe adjacency play,” says Rachita Rao, senior analyst at Everest Group. “The intent is to extend IBM Z and LinuxONE environments by enabling Arm-compatible workloads to run closer to systems of record. While hyperscalers use Arm to lower their own internal power costs and pass savings to cloud-native tenants, IBM is targeting the sovereign and air-gapped market.”

Amazon Imposes 3.5% Fuel Surcharge For Many Online Merchants

Published

on

An anonymous reader quotes a report from Bloomberg: Amazon will start charging sellers who use its shipping services a 3.5% “fuel and logistics” surcharge later this month, joining the ranks of shipping companies raising prices as the war in Iran pushes oil prices higher. The fees take effect on April 17 for customers of the company’s Fulfillment by Amazon service — which is used by many of the independent sellers who list their products on Amazon’s retail sites — in the US and Canada. Items shipped by Amazon on behalf of merchants who sell on their own sites or at other retailers will carry the surcharge beginning May 2. “Elevated costs in fuel and logistics have increased the cost of operating across the industry,” Ashley Vanicek, an Amazon spokesperson, said on Thursday. “We have absorbed these increases so far, but similar to other major carriers, when costs remain elevated we implement temporary surcharges to partially recover these costs.”

Vanicek notes that the fee will apply to the sum Amazon charges to ship an item, not the product’s sale price.

Last month, USPS announced that it would impose its first-ever fuel surcharge on packages.

Startup launched by former AWS energy team emerges with $7M to help solve data center power crunch

Soma Energy, a startup founded by former Amazon energy managers, emerged from stealth Thursday with $7 million in funding.

The Vancouver, B.C.-based company has built an AI platform serving power producers and data centers, helping both optimize their energy assets in real time to save money and extend their available power. The technology coordinates resources including wind, solar and batteries and the management of energy demands such as data center workloads.

CEO Ath Caramanolis said you can visualize an electrical system as a complex network of roads and highways on which electrons — instead of cars and trucks — are traveling.

“Our software is sort of a control plane that helps provide the self-driving for electrons on these highway systems,” Caramanolis said in a GeekWire interview.

More efficient routing of electron traffic can bring more power to bear for the grid’s competing needs.

“There is low hanging fruit everywhere, and the opportunities for large energy users like data centers to better utilize the grid exist all across North America,” Caramanolis said.

Industries, utilities and elected officials worldwide are racing to expand energy supply as data centers and electrification of transportation, heating and other sectors drive surging demand. Data centers alone are expected to more than double their power draw — from 82 gigawatts in 2025 to 219 by 2029 — with most of that growth fueled by AI, according to McKinsey.

Amazon hired Caramanolis in 2018 to create the energy optimization team at AWS, which managed about 10 gigawatts of renewable energy across its global network of data centers. Seattle City Light, by comparison, has a generation capacity of about 2 gigawatts.

Caramanolis then recruited Mario Souto, Soma Energy’s co-founder and chief technology officer, to build the machine learning platform AWS used to optimize its renewable portfolio. The startup’s third co-founder, Chief AI Scientist Henrique Hoeltgebaum, is an expert in AI-driven forecasting and anomaly detection for energy systems.

Soma Energy launched in February 2024 and has 18 employees. The startup has deployed 2 gigawatts of assets in the U.S. with customers including several independent power producers and five data center companies — among them H5 Data Centers, whose sites include a large facility in downtown Seattle.

“By coordinating existing resources, we were able to access capacity significantly sooner than expected, accelerating our time to power and removing a critical constraint on expansion,” said Josh Simms, CEO of H5 Data Centers, in a statement.

The seed round was led by Category Ventures, with participation from Haystack, Panache Ventures, RRE Ventures, TO.VC, Uncork Capital and Walter Kortschak. The investment will allow the team to hire new employees in engineering and commercial roles and expand its reach across North America.

“Having managed hyperscale power systems firsthand, the founders built Soma Energy as if they were the customer themselves,” said Villi Iltchev, partner at Category Ventures.

Anything Can Be A Router, If You Try Hard Enough

Published

on

If you’re an American and you use the Internet at home, it seems probable that routers are going to be in short supply. The US government recently mandated all such devices be home grown for security reasons, which would be fine were it not that the US has next-to-no consumer-grade router manufacturing industry.

So if you’re in the US and you need a router, what can you do? [Noah Bailey] is here from Canada to point out that almost anything (within reason) in computer terms can be made to perform as a router.

The piece is really a guide to setting up a Linux router, which he does on a small form factor PC and a hacked-together assembly of old laptop, PCI-express extender, and scrap network kit. In its most basic form a router doesn’t need the latest and greatest hardware, so there exists we’re guessing almost two decades of old PCs just waiting to be pressed into service. Perhaps it won’t help the non-technical Man In The Street much, but maybe it’ll inspire a few people to save themselves a hefty bill when they need to connect.

Windows 3.1 On A Modern AM5-Based PC Is Surprisingly Usable

Published

on

Although Windows 95 stole the show, Windows 3.0 was arguably the first version of Windows that more or less nailed the basic Windows UI concept, with the major 3.1 update being quite recognizable to a modern-day audience. Even better is that you can still install Win3.1 on a modern x86-compatible PC and get some massive improvements along the way, as [Omores] demonstrates in a recent video.

The only real gotcha here is that the AMD AM5 system with Asus Prime X670-P mainboard is one of those boards whose UEFI BIOS still has the ‘classic BIOS’ Compatibility Support Module (CSM) option. With that enabled, Win 3.1 installs without further fuss via a USB floppy drive from a stack of ‘backup’ floppies that someone made in the early 90s. [Omores] also tried it with CSMWrap, but with this USB to PS/2 emulation didn’t work.

Windows 3.1 supports ‘enhanced mode’ by default, which adds virtual memory and multi-tasking if you have an 80386 CPU or better. To fix crashing on boot and having to use ‘standard mode’ instead, the ahcifix.386 fix for the responsible SATA issue by [PluMGMK] should help, or a separate SATA expansion card.

For the video driver the vbesvga.drv by [PluMGMK] was used, to support all VESA BIOS Extensions modes. This driver has improved massively since we last covered it and works great with an RTX 5060 Ti GPU. There’s now even DCI support to enable direct GPU VRAM access for e.g. video playback, with audio also working great with only a few driver-related gotchas.
