SISSEJUHATUS ITSSE

USENET 1979 on hiiglaslik kogus uudisgruppe. Tekstid liiguvad masinast masinasse. Info liikus algselt: UUCP protolli abil (Unix to Unix communications protocol, enamasti moodemi abil sissehelistamisega). 1986 Uudised liiguvad TCP/IP (interneti) kaudu. 1981 Adam Osborne completed the first portable computer, the Osborne I, which weighed 24 pounds and cost $1,795. Used Z80 (NOT IBM-PC clone (yet)!) Apollo Computer unveiled the first workstation, its DN100, offering more power than some minicomputers at a fraction of the price. Used a Motorola 68000 microprocessor. College professor James Clark found Silicon Graphics, Incorporated. The 1000 and 1200 computers used a Motorola 68000 microprocessor with 8 Mhz and were sold as diskless systems intended for use as a terminal. IBM announces the CGA graphics card for the PC, giving 640x200 resolution with 16 colors. 1982 The ZX Spectrum is an 8-bit personal home computer released in the United Kingdom in 1982 by Sinclair Research Ltd

 Steve Wozniak writes the floppy disk controller software for use with the Apple II.  Dan Bricklin conceives the idea for the VisiCalc spreadsheet program.  IMSAI licenses use of CP/M for its microcomputers for US$25,000.  Atari introduces the Atari Video Computer System (VCS), later renamed the Atari 2600. 1978  The VAX 11/780 from Digital Equipment Corp. featured the ability to address up to 4.3 gigabytes of virtual memory, providing hundreds of times the capacity of most minicomputers.  The 5 1/4-inch floppy disk became the standard medium for personal computer software after Apple Computer and Tandy Radio Shack introduced disk drives for this format. January  Apple Computer demonstrates its first working prototype Apple II disk drive at the Consumer Electronics Show, in Las Vegas. May  Intel begins production of the 8086 microprocessor. It is created by two engineers in just three weeks. Work on the processor began when it was realized that the i432 project was in

outputs in terms of the inputs and either synchronous or asynchronous feedback from the outputs. Before PALs were introduced digital designers would use SSI (small- scale integration) components, such as 7400 series nand gates and D-flipflops. One PAL device would typically replace dozens of such 'discrete' logic packages, so the SSI business went into decline as the PAL business took off. PALs were used advantageously in many products, such as minicomputers, as documented in the best- selling book "The Soul of a New Machine." Early PALs were programmed using PALASM language files (converted by a compiler into JEDEC ASCII/hexadecimal files) and a special electronic programming system available from either the manufacturer or a third-party, such as DATAIO. Gang programmers were used when more than just a few parts were needed and for large volumes the manufacturer would fabricate a custom metal mask for
