DOOM Is Now Playable on a Coffee Machine, Because of Course It Is

The question of whether a device can run DOOM has become one of gaming's most enduring running jokes, but it is also a surprisingly useful measure of ingenuity. Over decades, id Software's landmark 1993 shooter has appeared on everything from traditional PCs and consoles to calculators, printers, medical equipment, lawnmowers, and even a PDF file. Now, a self-service coffee machine can be added to that extraordinary list.

A creator known on YouTube as rmassink, identified in technical project documentation as Robin M., has demonstrated a playable version of DOOM running on a Spengler PSL50 coffee machine. Rather than merely displaying a static image or a novelty menu screen, the machine appears capable of running the game properly through its built-in display, turning a device designed to dispense hot drinks into an unlikely demon-slaying station.

It is a fittingly absurd application for a game that has become synonymous with experimental ports. A customer would normally approach a kiosk such as the PSL50 to choose a cappuccino, espresso, or another coffee option. In this case, the touchscreen can instead be used to launch a first-person shooter from gaming history. There may be no practical reason to fight through a Martian base while waiting for milk to froth, but practicality has never been the point of the wider "Can it run DOOM?" tradition.

A coffee kiosk with enough computing power for a classic

The Spengler PSL50 is not a basic domestic coffee maker with a few buttons and a small clock display. It is a self-service coffee kiosk, the type of machine built to manage drink selections, on-screen interfaces, internal equipment, and customer-facing operation. That comparatively sophisticated setup gives it more in common with a dedicated embedded computer than a conventional countertop appliance.

Robin's project makes use of that embedded hardware. The process shown involves loading the needed material via a memory stick connected at the rear of the machine. The implementation reportedly takes advantage of very limited security protections on the coffee system, an understandable design decision for an appliance that is generally expected to make beverages rather than run unapproved software.

That lack of strong restrictions made the conversion possible, but it also puts the achievement in perspective. This is a tinkering demonstration, not a recommended upgrade for coffee-shop equipment or a feature intended for everyday users. Altering the software of any connected or commercial machine can disrupt its normal function, create maintenance issues, and potentially introduce security concerns. In this case, the normal coffee-making controls are effectively displaced while the game is active, which means it is not exactly an ideal way to serve a queue of thirsty customers.

Still, as a technical curiosity, it is hard not to appreciate. The sight of DOOM on a coffee interface captures precisely why the game has remained such a popular benchmark for hobbyists: it is recognizable at a glance, historically important, and lightweight enough that a vast range of hardware can potentially handle it with the right software work.

fbDOOM brings the shooter to the machine

The version used for the Spengler project is fbDOOM, a port intended for systems that can output through a framebuffer rather than requiring the sort of conventional desktop environment associated with a standard PC. That makes it especially suited to embedded devices, where the screen may be controlled directly and the hardware may be designed around a specialized interface rather than general-purpose computing.

For an appliance touchscreen, that matters. The PSL50 was never designed as a gaming platform, and it does not need the familiar layers of an operating system, launcher, storefront, controller ecosystem, or graphical user interface found on current consoles and PCs. A framebuffer-focused approach helps bridge the gap between the hardware's intended role and the needs of a game originally built for much older computers.

The demonstration indicates that the game is fully playable rather than simply booting to a title screen. That distinction is important in the long-running culture around unusual DOOM ports. Getting an image onto a display is one technical trick; loading levels, processing player input, rendering movement, and making the experience function as a game is another. The latter is what turns the coffee machine from a joke into a genuine porting accomplishment.

Exactly how one would settle in for an extended session at a coffee kiosk is another question. The machine's display and interface were built around drink choices, not comfortable game controls, and its position as a working appliance makes it a far less convenient venue than a PC, handheld, console, or phone. But convenience is not why people follow these projects. The delight comes from seeing a famous game escape the hardware boundaries people assume it has.

Why DOOM remains the ultimate porting challenge

DOOM is more than a beloved shooter; it has become a kind of shared technical language. Its engine, age, and cultural status make it an ideal target for programmers who want to demonstrate that an unexpected piece of hardware has enough capability to do something entertaining. The game is instantly legible. Even a brief glimpse of its corridors, weapon sprites, enemies, and status bar tells viewers exactly what they are looking at.

Its continued portability is also tied to the release of the game's source code, which has enabled a huge community to study, adapt, and maintain versions of the engine across countless systems. The original game's assets remain a separate consideration, but the availability of source code helped transform DOOM from a classic commercial release into a platform for technical experimentation.

Over time, the phrase "Can it run DOOM?" has shifted from a casual benchmark into a celebration of hardware hacking. The target device can be old, new, useful, obsolete, powerful, underpowered, or completely unsuitable. If it contains a processor, memory, a display, or some way to connect those pieces together, someone may eventually wonder whether it can host id Software's demon-filled classic.

The coffee-machine port follows a familiar pattern. First comes the unexpected hardware: in this case, a commercial self-service coffee unit. Then comes the discovery that the device is more capable than it appears. Finally, a tailored port proves that the hardware can do more than its manufacturers originally intended. It is a process that turns ordinary technology into a conversation piece.

A novelty with a real technical lesson

There is an easy temptation to dismiss projects like this as nothing more than a meme, particularly since the headline image is inherently funny: a person selecting DOOM next to coffee options. Yet there is meaningful technical skill behind the gag. Understanding an embedded device, finding a route for loading software, adapting a compatible port, and producing a playable result requires curiosity and persistence.

It also highlights the hidden computing power built into modern appliances. Many pieces of equipment now include screens, processors, storage, networking capabilities, and software stacks that would have been far beyond the requirements of older dedicated machines. They are designed to make a narrow task easier, but beneath the specialized exterior is often a small computer. The PSL50 demonstration is a playful reminder that those computers have capabilities beyond their assigned jobs.

That does not mean every appliance should become a gaming device. Machines used in businesses, especially those handling payments, customer data, or essential operations, should be kept secure and maintained for their intended purpose. The Spengler port is best viewed as a controlled hobby project and an amusing proof of concept, not an invitation to modify public equipment. A coffee machine that cannot make coffee because it is occupied by Doomguy is entertaining once; it is much less entertaining during a busy morning rush.

The legend keeps growing

For players, the most sensible way to enjoy DOOM remains using a proper gaming device. Modern PCs, consoles, handhelds, and officially supported rereleases offer far more comfortable controls, reliable performance, and convenient access. Nobody needs to reconfigure a beverage kiosk to revisit one of the most influential shooters ever made.

But that is beside the point. The Spengler PSL50 port joins the larger history of improbable DOOM projects because it is funny, inventive, and immediately understandable. It turns an everyday machine into a tiny piece of gaming folklore. The next time someone asks whether a device can run DOOM, the safest answer may simply be: probably, if a determined enough tinkerer gets hold of it.

For now, the coffee machine stands as another monument to the durability of a 1993 classic--and to the internet's refusal to leave any screen unexplored. Just do not expect to order an oat milk DOOMacino while the game is running.
