Transistors instead of vacuum tubes. Transistors are completely cold. It enables the machine to operate on fewer than 100 watts. -
PDP-1
The machine was sold for $120,000. They made 50 PDP-1. Hackers that work in MIT ( company which made the first ever computer game called space war) tested all 50 computers by playing the game on the computer. -
PDP-8
Digital Equipment Corp. introduced the PDP-8, the first commercially successful minicomputer. The PDP-8 sold for $18,000, one-fifth the price of a small IBM 360 mainframe. The speed, small size, and reasonable cost enabled the PDP-8 to go into thousands of manufacturing plants, small businesses, and scientific laboratories. -
8800
Bill Gates and Paul Allen licensed BASIC as the software language for the Altair. Ed Roberts invented the 8800 — which sold for $297 or $395 with a case— and coined the term "personal computer." The machine came with 256 bytes of memory (expandable to 64K) -
The Osborne 1
Adam Osborne completed the first portable computer, the Osborne I, which weighed 24 pounds and cost $1,795. The price made the machine especially attractive, as it included software worth about $1,500. The machine featured a 5-inch display, 64 kilobytes of memory, a modem, and two 5 1/4-inch floppy disk drives. -
OS/2
IBM introduced its PS/2 machines, which made the 3 1/2-inch floppy disk drive and video graphics array standard for IBM computers. The first IBMs to include Intel´s 80386 chip, the company had shipped more than 1 million units by the end of the year. -
neXT
Apple cofounder Steve Jobs, who left Apple to form his own company, unveiled the NeXT. The computer he created failed but was recognized as an important innovation. At a base price of $6,500, the NeXT ran too slowly to be popular. -
