Note 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. 
Configurations Internal HardDisk: 10 or 20Mb. External HarDisk: 20, 40 or 80Mb up to a maximum of 160Mb.
