Vector Graphic was an early microcomputer company founded in 1976, the same year as Apple Computer, during the pre-IBM PC era, along with the NorthStar Horizon, IMSAI, and MITS Altair. The first product was a memory card for the S-100 bus. A full microcomputer using the Z80 microprocessor, the Vector 1, was introduced in 1977. There were several Vector Graphic models produced. The Vector 1+ had a floppy disk drive.〔 The Vector Graphic 3 had a fixed keyboard which limited sales as detached keyboards were becoming popular. The Vector Graphic 4 was a transitional 8/16 bit hybrid model. Although primarily used with the CP/M operating system, it ran several others including OASIS, Micropolis Disk Operating System (MDOS), and Micropolis Z80 Operating System (MZOS). Early Vector Graphic models used the Micropolis floppy disk controller and Micropolis floppy disk drives. Later models were designed with the integrated Floppy Drive/Hard Drive controller and used Tandon floppy drives. Almost all used unusual 100 track per inch 5¼" floppy drives and 16 sector hard sector media. Some models included 8" floppy drives and hard disk drives. Vector Graphic sales peaked in 1982 at $36 million. It faltered soon after due to several factors. The introduction of the IBM PC in August 1981 shifted the market and smaller players lost momentum. The Vector 4 was accidentally pre-announced in April 1982, the same month that founder and chief hardware designer Robert Harp left the company after a dispute with cofounder (and wife) Lore Harp over control of the company. At the end of 1983 Lore Harp was also gone and venture capital investors took over. By the summer of 1985 only three dozen employees remained, down from a peak of 425 workers in 1982.〔(The Rise and Decline of Vector Graphic: Management Mistakes and IBM Crush Couple's Computer Venture ), August 20, 1985, by Daniel Akst, ''Los Angeles Times''〕 Chapter 11 bankruptcy followed in December 1985.〔(Vector Graphic Seeks Chapter 11 Protection ), December 25, 1985, by Daniel Akst, ''Los Angeles Times'', Retrieved August 3, 2015〕 A sought-for merger partner was not found and chapter 7 liquidation of remaining assets resulted in October 1987.〔(Firm With Storybook Start Has Sad Ending: Vector's Assets Liquidated ), October 20, 1987, by Barry Stavro, ''Los Angeles Times'', Retrieved August 3, 2015〕 Vector Graphic computers had many innovations, such as the Flashwriter integrated video and keyboard controller. Vector Graphic was known for their Memorite word processing application. When combined with the Flashwriter, the Vector Graphic Memorite software gave low cost word processing capability, which had previously only been available with dedicated word processors. As of 2007, Vector Graphic still had a small but active user community. ==See also== * Corona Data Systems - founded in 1982 by Robert Harp 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Vector Graphic」の詳細全文を読む スポンサード リンク
