Taligent

Taligent was founded jointly by Apple and IBM in 1992, the company, which had the task to develop a fully object -oriented and platform- independent operating system. This cooperation also later used by Apple PowerPC platform was created.

History

The 1984 advanced Macintosh operating system had some design flaws that could only be corrected by a new development. The system does not support preemptive multitasking, multiuser mode, memory protection nor dynamic memory management so it was very prone to instabilities. This is why Apple decided a new operating system from scratch to develop:

Pink and Blue

1988, all the ideas were (English: pink) on pink during the planning of the Successor of Macintosh System 6 index cards held that could be realized from scratch developed system in one. All ideas that appeared in a new version of the existing system were implemented 6, to blue (English: blue) written index cards. From the blue card system was introduced in 1991 7 (codenamed "Blue Meanies " )

In 1988, the Project Pink was launched. Pink had a totally object-oriented operating system to the target, which should feel for the user as System 6. It was written in C and should already be able to run existing applications. Pink enabled documents, very easy to change between computers and users and to work together. It introduced a component-based document model, which made ​​it very easy to insert the contents of any program in any document. Later arose from this development OpenDoc.

Soon it came within Apple rivalry between the "Blue" - and the "Pink" team, which ended with the fact that the two teams were merged into one team.

In mid-1991 succeeded Apple, the company IBM to convince them of his development at that time, which is why the joint subsidiary Taligent was founded to accomplish Pink together. Soon they realized, however, that the market away from Apple did not need a new operating system, which is why Pink in Talae ( Taligent Application Environment; later Commonpoint called ) was converted. This left the problem persists the outdated Mac OS from Apple.

Common Point

The software product of Taligent was not a complete operating system anymore, but a runtime environment that was on AIX, HP- UX, OS / 2, Windows NT, and the resulting at Apple in Copland operating system to run. From the end of 1994, the company Hewlett -Packard participated in the development of Common Point. Quite a flop was the commercial release of Common Points for AIX and OS / 2 in 1995. As in the same year, the CEO of Taligent Dick Guarino died unexpectedly and Apple the project Copland higher priority, developing quickly came almost to a standstill.

The heirs

Apple and HP withdrew in 1995, and IBM took over the company completely Taligent. Some parts of Common Point were incorporated into Lotus Notes, and others were sold to the company Sun, Oracle and Netscape.

In 1996, IBM published the popular building on Common Point Model View Presenter (MVP).

In 1997, when Bill Gates was asked what turns and developments in the software industry really took him by surprise in the last 20 years, his response was: " Kaleida and Taligent had less impact than we expected. " ( " Kaleida and Taligent had less influence than we thought. " )

In January 1998, the company Taligent was dissolved and the then remaining staff moved to IBM in order.

The name Taligent

The name is a portmanteau word, from the English terms " talent" ( German: talent ) and " intelligent" ( German: intelligent). Bearing in mind that (a reference to Windows NT) and (a reference to the chip manufacturer Intel ) may be omitted "ent" " Smarter ".
