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.
Announced in 1998, the RS/6000 43P Model 150 was an entry-level desktop workstation powered by an IBM 375MHz PowerPC 604e processor.
The machine could support up to 1GB of RAM and ran the AIX OS. It had five PCI adapter slots and three media bays.
The PC was withdrawn from sale in 2003.
This IBM ThinkPad 770X was a high-end machine at the time of its release in the late 1990s.
It featured a 300MHz Intel Pentium II processor, 128MB of memory, a 14.1-inch TFT screen.
The PC weighed seven pounds and had a battery life of four hours.
