MB-02 (a prototype) was originally developed by MDV (Robert Letko) and Busysoft (Slavomir Labsky) - hence the name: [M]DV + [B]USY, 02 was a version of the system.
"8BC acquired the scheme and an operating system from these gentlemen and started producing MB-02+ (the "Plus" version had some nice improvements over the prototype). MB-02+ was a professional, although hand made, product. We were selling this approximately between 1995 and 2003. We sold some 70 pieces."
