About the Research Machines Ltd. Nimbus 186
This is a rare PC. Use a Intel 80186, instead the more common on PC's 8086 or 286 (80286). The Nimbus was designed as network machine and most of them came with a built-in network. They also use a 50ohm coaxial cable, like the networks of the time (Ethernet 10BaseT and Token Ring). The Nimbus can run on two modes: Nimbus mode wich gives access to the extended graphics and sound capabilities IBM mode. In this mode they emulate a IBM PC via software. It's like a XT with CGA. Althoug the RM MS-DOS 3.10 are MS-DOS compatible, they don't works on PC's.
