3+Open LAN Manager

3Com originally released the product in 1988 as 3+Open LAN Manager with server support for OS/2 and client support for OS/2 and DOS. Apple Macintosh support was added later. It was based on the earlier DOS-based NOS 3+Share. 3Com lost interest in the product and by 1991 had sold their codebase to Microsoft.
