Abstract

A multiple computer system having team/work group features built in. A principal hardware component thereof is a unitary chassis of a compact tower configuration, designed to house electronics for up to four personal computers, all operating on a single power supply. The unitary chassis provides interconnecting cable for connecting up to four corresponding display terminals and keyboards. One of the personal computers in the chassis is designated the TEAMHUB and the remaining personal computers in the chassis are designated TEAMMATES. Up to three such TEAMMATES may be included in one such chassis. Two TEAMPRO systems may be readily combined to serve up to eight local users in a team/work group environment. Each such computer electronics within the TEAMCHASSIS provides a communication card, which may for example be a SCSI card providing data rate transfer between TEAMHUB and TEAMMATES at 10 Megabytes per second. Furthermore, within the TEAMCHASSIS, each computer comprises a CPU card and a monitor interface card, such as a VGA card. In addition, the chassis provides at least one 51/4 inch floppy disk drive and at least one 31/2 inch floppy disk drive, both of which can be shared by any of the four computers in a daisy chain configuration. In addition, each computer has its own hard disk drives. The system is also designed to connect to external devices, such as CD-ROM or other SCSI devices.

Claims

1. A unitary chassis having a multiple computer system contained therein and comprising:

a plurality of CPU circuits, each such CPU circuit corresponding to a distinct computer;

a plurality of bus intercommunication circuits for data communications between said computers, each said bus intercommunication circuit corresponding to a distinct computer;

a plurality of display monitor control circuits for controlling display monitors, each such display monitor control circuit corresponding to a distinct computer;

said pluralities of CPU circuits, bus intercommunication circuits and display monitor control circuits being contained and electrically interconnected within said unitary chassis; and

at least one power supply within said chassis for powering all of said circuits; and

wherein said chassis comprises a six-sided housing having a pair of rectangular side panels, each such panel having a plurality of slots for providing access to said circuits of said chassis, one such rectangular side panel being a duplicate of one-half of the other such rectangular side panel and leaving an opening in said housing for removal and replacement of said circuits.

2. The unitary chassis recited in claim 1 further comprising a plurality of hard disk drives within said chassis and wherein each said CPU circuit is electrically connected to a respective corresponding hard disk drive.

3. The unitary chassis recited in claim 1 further comprising at least one floppy disk drive within said chassis, said CPU circuits all being electrically connected to said floppy disk drive.

4. The unitary chassis recited in claim 1 wherein at least two distinct computers are contained therein.
