Abstract:
A local area network (LAN) system comprising:multiple data processing subsystems concentrated into a small volume of space comparable to the space occupied by a presently conventional personal computer; a storage subsystem managed by one of said processing subsystems; and a bus connected directly to said storage subsystem and each of said processing subsystems; wherein: said bus is controlled directly by individual of said processing subsystems to enable said processing subsystems to individually obtain direct access through said bus to said storage subsystem; said bus is operated at a speed sufficient to enable each said processing subsystem to coordinate its real-time program execution processes with accesses to said storage subsystem via said bus, whereby information obtained by such accesses is immediately useful to sustain a said real-time process; and wherein said processing subsystems are connected to a coaxial cable containing 3 signal bearing lines; a first one of said lines being used to carry information in an unmodulated form constituting intelligence for forming a video display, a second one of said lines being used to carry data in modulated form between said card and said remote equipment, and a third one of said lines being used to carry signals for synchronizing reception of data sent from said card to said remote equipment and transmission of data sent from said remote equipment to said card.
