The OSM Zeus 3X is a Z80 based multi-user computer that supports a single hard drive (from 12 to 140 Mb) and up to 32 users (8 only for the Zeus 4) via dumb terminals plugged into RS232 ports. The ports supports several terminal emulations as well as serial printers and modems.
The Zeus computer uses MUSE (Multi User System Executive) as its operating system, a CP/M compatible OS for multi-user computers from OSM. It incorporates all the standard features of CP/M, while adding file management capabilities such as multi-user file sharing, password protection, print spooling, data security and auto-searching. Later, the ZMOS operating system, another multi-user CP/M compatible OS, was also available.
In the november 1984's issue of Computerworld, there is an article describing how Pepsi bought and used Zeus 3X computers to help them cope with orders processing through these multi-user file sharing systems.
