The first of the IBM Aptiva PC family was announced in September 1994 as a replacement for the PS/1 line. It was sold until May 2001, when IBM pulled out of the home computing market.
Initially PCs in the Aptiva brand were powered by Intel 486 processors, while later models had more powerful Intel Pentium and AMD CPUs.
Like the PS/1 family Aptiva PCs were sold as bundles that included the monitor, keyboard, mouse and speakers, as well as an installed operating system. During the lifetime of the family that OS changed from PC DOS/Windows 3.1 to the OS/2 Warp.
The Aptiva shown here is a Machine Type 2138 Model E82.
The design of the ThinkPad 701 allowed it to pack an 11.5-inch keyboard into a 9.7-inch notebook.
When the lid of the machine, released in 1995, is opened up the full-size keyboard unfolds and slides into place.
As later ThinkPads featured larger screens the need for a fold-out keyboard was eliminated and the 701 was the only ThinkPad to use this "Butterfly" keyboard.
The 701 is powered by a 486DX4/75 processor and weighs only 4.5 pounds.
The "Butterfly" keyboard won plaudits for its design and was put on display at the Museum of Modern Art in New York.
This IBM Intellistation computer, a workstation-class PC first released in 1997, is running IBM Network Station Manager under Windows 2000 Server.
Network Station Manager is the software needed to boot and manage a group of IBM Network Stations.
The Network Station is connected to this server via TCP/IP over a Token ring LAN, a networking protocol now not commonly used.
Unlike Ethernet technology, Token ring passed a "token" between stations. Only a station in possession of a token could transmit on the LAN, thus avoiding collisions and therefore giving a more deterministic performance.
The advent of Ethernet switching largely removed the disadvantages of Ethernet's protocol and thus today it's the primary LAN of choice.
