A Raspberry Pi RP2350 chip emulates a 1990s Apple Macintosh, running legacy software like Photoshop and WordPerfect at a fraction of the original cost.
This experiment highlights the dramatic reduction in computing costs and power consumption while questioning modern software bloat. It suggests low-cost, low-power devices could still handle basic productivity tasks, offering alternatives for resource-constrained environments or users seeking simplicity.

A £0.60 Raspberry Pi RP2350 chip emulates a 1990s Macintosh, running Photoshop and WordPerfect with minimal hardware.
The emulated system demonstrates that modern computing power far exceeds what is needed for many basic tasks, raising questions about software efficiency.
Low-power, low-cost devices could enable simpler, more sustainable computing solutions for specific use cases or environments.
THE READ
What the cluster adds up to.
The experiment demonstrates that a £0.60 microcontroller, the Raspberry Pi RP2350, can emulate a 1990s Apple Macintosh with sufficient performance to run legacy software like Photoshop and WordPerfect. This is achieved with two 150MHz processors, 4MB of RAM, and gigabytes of storage, which were standard specifications for mid-1990s computers. The emulation is not flawless, graphics are monochrome, and performance is limited, but it proves that modern hardware can replicate decades-old computing capabilities at a fraction of the original cost and power consumption.
The cost comparison is stark: a Macintosh SE from 1989, adjusted for inflation, would cost thousands of pounds today, while the RP2350-based system can be built for a few pounds. This underscores how hardware costs have plummeted, even as software complexity has grown. The experiment also raises questions about whether modern computing needs, such as document editing, email, and web browsing, could be met with far simpler, more efficient systems. However, the limitations are clear: modern web standards, high-resolution media, and real-time communication remain out of reach for such low-power devices.
The project explores the trade-offs between simplicity and functionality. While the emulated system lacks the distractions of modern operating systems, it also cannot handle tasks like video playback or complex web browsing. This suggests potential use cases for ultra-low-power devices in environments where resources are limited, such as remote areas or for users who prioritize sustainability and minimalism. The experiment aligns with movements like Permacomputing and Solarpunk, which advocate for sustainable, repairable, and user-modifiable technology.
Practical applications could include lightweight laptops with e-paper displays, solar-powered devices, or dedicated systems for specific tasks like music playback or messaging. However, challenges remain, such as integrating modern networking standards (e.g., 4G/5G) or handling the complexity of contemporary web content. The project also highlights the potential for simpler interfaces to reduce digital addiction and improve focus, though this would require a shift in software design priorities away from constant connectivity and notifications.
