The Nokia MikroMikko 4 M348 — Finland’s 486 Desktop
The Nokia MikroMikko 4 M348 was a 486-class desktop computer in the MikroMikko 4 series — one of the final and most powerful configurations in Nokia’s domestic computer line before the division was sold to ICL in 1991. The M348 model number indicated a 486DX configuration, bringing Intel’s most capable processor of the early 1990s to Finland’s domestic computer brand. At the time of its production, the 486DX represented the cutting edge of PC performance, with its integrated floating-point unit delivering dramatic improvements over 386-class machines for demanding professional applications.
The 486 Generation
Intel’s 80486DX processor, introduced in 1989, was a landmark chip — integrating the floating-point unit directly on the processor die (previously requiring a separate coprocessor), doubling the on-chip cache to 8 KB, and delivering roughly twice the performance of a 386DX at equivalent clock speeds. For Finnish businesses running CAD software, database applications, and the increasingly demanding office productivity software of the early 1990s, the 486’s performance advantage was immediately and practically significant.
Nokia’s Final Chapter in Computing
The MikroMikko 4 M348 represents Nokia’s computing division at its most technically capable — and at the end of Nokia’s ownership. The sale to ICL in 1991 marked Nokia’s strategic exit from personal computing as the company concentrated on the telecommunications business that would make it globally famous. The M348 is thus a historically poignant machine: the most powerful computer produced under Nokia’s ownership, built just as Nokia was preparing to leave the computer business that had occupied a significant part of its operations for a decade.
