The PowerBook G3 is a line of laptop Macintosh computers produced by Apple Computer between 1997 and 2001. It was the first laptop to use the PowerPC G3 (PPC740/750) series of microprocessors. It was succeeded by the Titanium PowerBook G4 line in 2001, which used the PowerPC G4 (PPC74xx) series of microprocessors.
PowerBook G3 (Kanga)
The first Macintosh PowerBook G3, code-named "Kanga," was introduced in November 1997. At the time of its introduction, the PowerBook G3 was advertised as the fastest notebook computer available (a title formerly held by its predecessor, the 240MHz PPC-603ev-based PowerBook 3400c). This model was based on the PowerBook 3400c, and was unofficially known as the PowerBook 3500. It used the same case as the 3400c, and a very similar motherboard. The motherboard was upclocked from 40MHz to 50MHz, resulting in some incompatibility with older 3400 RAM modules. Other changes to the motherboard included doubling the on-board RAM from 16 MB to 32 MB, and a faster version of the on-board Chips and Technologies graphics controller. The G3 made the Kanga more than twice as fast as a 3400c, and the improved graphics controller allowed it to refresh the screen 74 percent faster.
A general contractor (main contractor, prime contractor) is responsible for the day-to-day oversight of a construction site, management of vendors and trades, and the communication of information to all involved parties throughout the course of a building project.
The general contractor is a manager, and possibly a tradesman, employed by the client on the advice of the architect, engineer or the architectural technologist or the client him/herself if acting as the manager. A general contractor is responsible for the overall coordination of a project.
A general contractor must first assess the project-specific documents (referred to as bid, proposal or tender documents). In the case of renovations, a site visit is required to get a better understanding of the project. Depending on the project delivery method, the contractor will submit a fixed price proposal or bid, cost plus price or an estimate. The general contractor considers the cost of home office overhead, general conditions, materials and equipment as well as the cost of labor to provide the owner with a price for the project.
