Notebook Computers: Toshiba America Information Systems Inc. in Irvine is shipping three of its notebook computers with Microsoft's new DOS 6.0 operating system, which governs the basic functions of a personal computer.
The notebook computer models include the Satellite T1900, T4500 and T4600. Notebook computers are portable and weigh less than eight pounds. The models will be sent out with the operating system already installed on their hard disk drives.

Toshiba also said it signed an agreement with Office Depot Inc. to distribute its Satellite Series notebook computers in 314 Office Depot stores nationwide.
