Dubna 48K

The Dubna 48K was a Soviet-era clone of the Sinclair ZX Spectrum home computer. It was produced in the town of Dubna, near Moscow, hence its name. The "48K" refers to the 48 kilobytes of RAM that the machine possessed, matching the memory capacity of the popular ZX Spectrum model it emulated.

Like many Soviet and Eastern European clones of Western computers, the Dubna 48K was produced due to limited access to foreign technology during the Cold War. These clones aimed to provide access to computing technology and software that was otherwise difficult or impossible to obtain legally.

The Dubna 48K, while intended to be compatible with ZX Spectrum software, often suffered from slight incompatibilities due to differences in hardware implementation and manufacturing tolerances. This could lead to some software failing to run correctly or exhibiting graphical glitches. Despite these issues, it provided a vital opportunity for many Soviet citizens to experience home computing and engage with a growing community of programmers and hobbyists. The computer was typically used for games, educational purposes, and basic programming.
