Abstract

As the use of intelligent computer workstations increases, it is becoming more common for a user to require more than one workstation in the work environment. Although the user has multiple workstations which may be running simultaneously, normally the user will interact with only one of the workstations at a time. In the past, it was required to have a set of input/output devices for each workstation, such as keyboards, printers, graphic tablets, and the like. The system to be described provides a method for selectively connecting any of a single set of input/output devices to any one of a number of workstations as required by the user.

Peripheral Connector Assembly With Device Sharing

As the use of intelligent computer workstations increases, it is becoming more common for a user to require more than one workstation in the work environment. Although the user has multiple workstations which may be running simultaneously, normally the user will interact with only one of the workstations at a time. In the past, it was required to have a set of input/output devices for each workstation, such as keyboards, printers, graphic tablets, and the like. The system to be described provides a method for selectively connecting any of a single set of input/output devices to any one of a number of workstations as required by the user.

Referring to the figure, it can be seen that a central control device, called a peripheral connector assembly, controls the interconnection of input/output devices with intelligent workstations.

Devices number 1, number 2 and number 3, respectively, may be, for example, a keyboard, a display monitor and a printer, whereas workstations 1 and 2 may be a graphics workstation and an alphanumeric text workstation, respectively. The peripheral connector assembly would allow, for example, the keyboard and monitor to be connected to the alphanumeric workstation while the printer is connected to the graphics workstation for printing.

The peripheral connector assembly may typically include a micro- controller which, in turn comprises a microprocessor, a small random- access memory and a rea...
