Taligent
Taligent was a company founded jointly by Apple and IBM in 1992 with the task of developing a completely object-oriented and platform-independent operating system. This cooperation also later used by Apple emerged PowerPC - platform .
Together Apple, IBM and HP developed the runtime environment later known as CommonPoint for different operating systems. Development at Apple began in 1988 as the "Pink" operating system project , which was later further developed as TalOS together with IBM , but was eventually discontinued. After Apple withdrew, the project was initially renamed TalAE as a runtime environment , later renamed CommonPoint , and has since been further developed together with HP.
CommonPoint ceased development in 1998.
history
The Macintosh System Software operating system , which has been further developed since 1984 , had some conceptual deficiencies that could only be remedied by a new development. The system did not support preemptive multitasking , multi-user operation , memory protection or dynamic memory management , which is why it was very prone to instabilities. So Apple decided to create a new operating system from scratch:
Project Pink
1988 of the successor were on during the planning system 6 all ideas on pink ( english pink ) index cards held that could be realized from scratch developed system in one. All ideas that implement released in a new version of the existing system 6 were on blue ( English blue letters) index cards. The blue cards became System 7 in 1991 . (The development team was appropriately named " Blue Meanies " - a reference to characters from the Beatles' film Yellow Submarine .)
In 1988 the "Pink" project was started. "Pink" aimed for a completely object-oriented operating system that should feel like System 6 to the user. It was written in C ++ and should be able to run existing applications. "Pink" made it possible to exchange documents very easily between computers and users and to work on them together. It introduced a component-based document model that made it very easy to insert content from any program into any document. This development later resulted in OpenDoc .
Soon there was rivalry within Apple between the “ Blue ” and the “Pink” teams, which ended with all employees being combined into a single team.
TalOS and TalAE
In mid-1991, Apple succeeded in convincing IBM of its development at the time, which is why the joint subsidiary Taligent was founded in order to jointly complete "Pink" under the new name TalOS. It soon became apparent, however, that the market apart from Apple did not need a new operating system, which is why the project was further developed as a runtime environment ( English Application Environment ) TalAE, for English Taligent Application Environment .
When Apple saw no need for TalAE after 1995, it withdrew from development and left IBM the sole further development of the runtime environment. IBM renamed TalAE CommonPoint and integrated it into its own products.
For Apple, however, the problem of the outdated classic Mac OS remained.
CommonPoint
TalAE became a runtime environment under the name CommonPoint , which could run on AIX , HP-UX , OS / 2 , Windows NT and the operating system being developed at Apple in Copland . From the end of 1994, Hewlett-Packard also participated in the development of CommonPoint. A failure was / 2 in 1995. When the commercial release of Common Point for AIX and OS in the same year, the CEO , died of Taligent, Dick Guarino unexpected and Apple the Copland project prioritized higher, the development came quickly almost to a standstill.
The heirs
Apple and HP withdrew in 1995, and IBM took over Taligent entirely. Some parts of CommonPoint flowed into Lotus Notes and others were sold to the companies Sun , Oracle and Netscape .
In 1996, IBM released the popular CommonPoint-based Model View Presenter (MVP).
When in 1997 Bill Gates was asked what turns and developments in the software industry had really surprised him over the past 20 years, his answer was: “ Kaleida and Taligent had less impact than we expected.” “Kaleida and Taligent had less impact than we thought.")
In January 1998 the Taligent company was dissolved and the remaining employees were taken over by IBM.
The name Taligent
The name is a suitcase word , from the English terms " tal ent" (German: talent ) and "intell igent " (German: intelligent) - where "e nt " (an allusion to Windows NT ) and " intell " (an allusion to the chip manufacturer Intel ) were omitted.
