Since 1976, the company reinvented itself repeatedly, as it has developed and improved the Macintosh, which affect the world of computer whenever did. Macintosh or Mac, is a line of personal computers designed, developed and marketed by Apple after its introduction in 1984.
Now, we will make a historic journey and learn how evolution has led to the revolution Apple Mac.
The Apple I
Sold as a board of circuit assembly, it lacks basic features such as a keyboard, monitor, and case. It was sold as a motherboard (with CPU, RAM chips and basic textual-video) less than what is today considered a complete personal computer. The Apple I was sold in July 1976 and was the market price of $ 666.66.
The Apple II was introduced April 16, 1977, and it differs from its main rivals, the TRS-80 and Commodore PET, because it came with color graphics and open architecture. While early models used ordinary cassette as storage devices, they were replaced by the introduction of a 5 1 / 4 inch floppy drive and interface, the Disk II.
Apple Lisa
With a price of $ 10,000, was released in 1981 and remembered as one of the most disappointing Apple. Was a system more advanced than the Macintosh of the day in many ways, its inclusion as protected memory, cooperative multitasking, a disk drive generally more sophisticated based operating system, a high-screensaver, an advanced calculator with paper tape and RPN, in support up to 2 MB of RAM, expansion slots, and greater display resolution higher.
Mac 128K
Apple launched the Macintosh in a famous 1984 Super Bowl with a beige box that contains a 9-inch screen and comes with a keyboard and mouse. There was a sale price of $ 2,495. It has 8 MHz Motorola 68000 microprocessor, 128 kbytes of DRAM, 64 KB ROM chip that boosts effective memory to 192 KB.
Mac II
Retailing for U.S. $ 3898 base price (for CPU only), the Macintosh II was the first "modular" model of Macintosh and called because it came in a horizontal desktop case like the PC era. He introduced the space for an internal hard drive (originally 20 MB or 40 MB) and a second optional floppy drive.
Mac Notebook
It was Apple's first attempt to provide a battery Macintosh laptops that had the power of a Macintosh desktop. It was released in September 1989 and received with enthusiasm by most critics but with very poor sales to consumers. With a price of $ 6500, it offered a B & W screen active matrix LCD, ergonomic keyboard, trackball and battery lead acid for the life 10 hours. He used expensive SRAM in an effort to maximize battery life and provide an instant "on" mode for low power sleep.
The 20th Anniversary Mac
To celebrate its 20th birthday, January 7, 1997 Apple has unveiled the limited edition of the Twentieth Anniversary Macintosh (PRE) the MacWorld Expo in San Francisco.
At $ 7,499 the 603rd MNT included a 250 MHz processor, 12.1 "active matrix LCD with 2 MB of VRAM, 4x CD-ROM, 2 GB ATA hard drive, mounted vertically drive Apple SuperDrive, and a TV / FM tuner, S-Video card, and a custom-made Bose sound system. It has a trackpad instead of a mouse, which could be detached from the keyboard if desired. When not needed, the keyboard can slide under the head of the unit of TAM, leaving exposed the trackpad for permanent access.
iMac
Introduced in 1998, iMac is a line of all-in-Macintosh desktop one. The original form of all, the iMac G3 is egg-shaped with a CRT monitor, bounded by colored, translucent plastic. In the second revision, the iMac G4, moved to the design of a hemispherical base containing all major components and an LCD monitor on an arm to move freely attached to the top of the base. The iMac G5 and iMac Intel put all the components immediately behind the screen, creating a slim design which tilts up and down on a simple metal base.
Earlier this year, Apple has updated its offerings for the iMac with NVIDIA chipsets and the new Mini DisplayPort.
MacBook Air
On January 15, 2008, the company launched its the ultraportable MacBook Air, a computer the company described as the thinnest laptop in the world, offered from $ 1799. Sporting a silvery finish, the MacBook Air has an LED 13.3 inch widescreen display with backlight that has a 1280 x 800 pixels resolution. It weighs about 3 pounds and sports a thickness of 0.16-0.76 inches. It is 12.8 inches wide and 8.95 inches deep.
Several features have been sacrificed to reduce size and weight machine. It is Apple's first notebook since the PowerBook 2400c without a built-in drive to removable media. It also omits a FireWire port, Ethernet port, line-in locations card and a Kensington security. The battery is internal, not user removable RAM is soldered onto the motherboard.
