Apple and IBM had two working relationships over the years. The 1991 alliance achieved a little more integration of Macs into the corporate world, but the PowerPC chip was its major accomplishment. In 2014, Apple and IBM agreed to create iPad applications for sale by both companies, and some apps were developed.
The 1991 Alliance
In 1991, Apple and IBM agreed to do the following.
1. Along with Motorola, to develop the PowerPC, a single-chip version of IBM's Power Architecture.
RESULT: The PowerPC was used in Macs, IBM midrange computers and embedded systems. See PowerPC
2. To better integrate Macs into IBM enterprise networks.
RESULT: A tad more network integration took place. IBM routers could connect to Apple networks, and a Mac Token Ring adapter was developed.
3. To develop PowerOpen, a Unix-based operating system that runs AIX and Mac applications on the PowerPC.
RESULT: Abandoned. IBM stayed with AIX, and Apple eventually wrote the Unix-based Mac OS X.
4. To form Taligent, Inc. to develop an object-oriented operating system for the PowerPC, Motorola 68xxx and Intel x86 families.
RESULT: The OS never came about. Taligent did deliver its CommonPoint application frameworks and development tools and was eventually folded back into IBM.
5. To form Kaleida Labs to develop and license multimedia software, tools and scripting languages for computers and consumer electronics.
RESULT: Kaleida introduced its ScriptX multimedia technology in 1995. It soon closed its doors and moved into Apple's Multimedia Group.
