Its claim to fame was its robust IBM PC compatibility paired with superior performance and graphics for its time, making it a strong alternative to IBM\u2019s own offerings and propelling Olivetti to become the leading PC manufacturer in Europe by 1986 and the third largest worldwide. The M24\u2019s importance lies in its role as one of the first successful European IBM-compatible PCs, helping to standardize DOS compatibility and expand the global PC ecosystem.<a
