An entire Atari 8-bit computer is recreated on a stamp-sized FPGA module
Atarino recreates full Atari 8-bit computer, fits in 2x1.5 cm, upgraded to 31 MHz.
In an impressive blend of nostalgia and cutting-edge technology, a Polish engineer named Piotr Ostapowicz has developed a miniature version of the classic Atari 8-bit computer. Dubbed the Atarino, this innovation fits Atari's comprehensive computer system onto a tiny FPGA module measuring just 2x1.5 cm. Originally launching in 1979, the Atari 8-bit computers occupied an entire desktop and sold for between $549 and $999. The Atarino manages to include all critical components such as the 6502C processor, graphics, sound chips, and memory controllers, reflecting a significant technological advancement compared to its massive predecessors.
Atarino's development started over a decade ago with Ostapowicz initially embarking on a simple compatibility test according to the detailed reports shared on the AtariAge forums. However, the project evolved significantly, ultimately leading to an improved recreation of the Atari XL/XE architectures. Unlike many retro mini consoles utilizing software emulation, Atarino employs FPGA technology to replicate Atari’s original components directly at the hardware level. This approach allows the Atarino to run vintage software on its recreated circuitry, supporting original peripherals and closely mirroring the functions of original Atari systems.
The Atarino outperforms the original hardware, running at speeds up to 31 MHz—far beyond the original machines' modest 1.79 MHz. This enhancement is achieved through an improved memory architecture replacing the “cycle stealing” method with independent channels, significantly boosting performance. Additionally, the Atarino provides support for extended graphics modes and outputs video via both VGA and HDMI connections. These features make Atarino not just a nostalgic relive but a powerful piece capable of handling more demanding tasks, demonstrated by real-time graphics processing of 4K animations.
While Atarino has not been released as a finished product, there are ongoing efforts to refine its features. Current development focuses on sound emulation, specifically enhancing the POKEY sound chip, and improving support for modern development environments such as CC65 and Visual Studio Code. The plan includes releasing comprehensive kits alongside documentation which will facilitate other developers and retro enthusiasts in creating their projects. This step is essential for spreading access and knowledge about integrating Atarino into various custom solutions.
The historical significance of Atari computers in Poland adds unique cultural and nostalgic value to this project. Despite stringent restrictions on Western technology in communist Poland, Atari systems became notably popular thanks to the efforts of Jack Tramiel, Atari's Polish-born owner, to introduce his systems to the Polish market. Therefore, while Atari's presence dwindled in the US by the 1990s, they maintained firm roots in Poland, supporting a thriving community of users and developers. Atarino signifies a continuation of this vibrant Atari legacy, paralleling technological innovation with cultural heritage.
