NetWare 5.x
Novel NetWare was an early and powerful network/file sharing operating system. It was first released in 1983 and supported DOS and CP/M clients and was initially unique in that it shared individual files rather than entire disk volumes. Initially servers ran on a proprietary Motorola 68000 system but quickly changed to IBM PC where it supported a very wide variety of third party hardware. It used a cooperative tasking server environment and had some advanced features usually only found in mainframe products.
