Apple

Apple company is the world’s second largest information technology company by revenue. Apple Company was founded on April 1, 1976 by Steve Jobs, Steve Wozniak and Ronald Wayne at Los Altos.
World’s largest technology company by total asserts
World’s third largest mobile maker
Apple Series:

Apple Ι

At the first time the company was founded for selling the Apple Ι Computer. It was designed and hand built by Steve Wozniak. At that time its price was 666.66$ Wozniak likes repeating digits so that Jobs fixed the price as 666.66$. This computer contains assembled circuit with 60+ chips. It did not have any graphical user interface, any programming language.
Apple ΙΙ Series:
Apple ΙΙ:

Apple ΙΙ was introduced in June 10, 1977. It was primarily developed by Steve Wozniak. Audio cassette is used for loading program and storing data. Later it was replaced by the floppy disk drive used for storing and retrieving process. The memory capacity of RAM is 4KB. It contains upper case only keyboard with 52 keys. Display and graphics uses NTSC television signal standard for colors.PCB board were manufactured in Ireland and Singapore. Apple ΙΙ was one of the most recognizable and successful computers during 1980 to 1999s. It was the first computer that went on sale with MOS technology 6502.
Apple ΙΙ plus:

Apple ΙΙ plus was introduced in June, 1979. Which included the Applesoft BASIC programming language in ROM, it was authored by Microsoft and later primarily used for floating point arithmetic operations on Apple ΙΙ and became the standard BASIC dialect of Apple ΙΙ series. Graphics and disk booting systems are improved in Apple ΙΙ plus. It contains 48KB built-in memory. Except that changes it was identical to Apple ΙΙ.
Apple ΙΙ Europlus and J-Plus: After the success of Apple ΙΙ series the company expanded their market into Europe, Australia (Europlus), Japan (J-plus). But in the most part Apple ΙΙ was same as the Apple ΙΙ Europlus and J-plus, but only the Apple keyboard layout was changed in Japanese version to allow for writing katakana (Japanese syllabary). In other countries it was sold with an unmodified American keyboard.
Apple ΙΙe:

Apple ΙΙe was developed in 1983 followed by Apple ΙΙ plus, ‘e’ indicates the enhanced version of Apple ΙΙ. When Apple ΙΙΙ was introduced in 1980 the company discontinued the versions of Apple ΙΙ but it didn’t reach its goal it lead to the recreation of Apple ΙΙ series. Apple ΙΙ was implemented in addition with full AsCII character set and keyboard, It has the one important feature that is the ability to input the lower case letters, Four way cursor control was initially implemented in this system. It uses the ProDOS operating system specially created for Apple ΙΙe. The memory capacity is expanded into 128KB of RAM and 16KB of ROM. It contains a special auxiliary slot that accepts 1KB memory card. It was the most popular Apple ΙΙ computer which was called as the ‘workhorse’ of the line. It was the only long-last lived apple computer that was manufactured and sold with minor changes for 10 years.

It contains 128KB RAM. It support DHGR (Double High Resolution Graphics) mode for display. Apple ΙΙc was the first microcomputer that uses Dvorak Simplified Keyboard which used less finger motions and reduces error compared to the standard QWERTY.
Apple ΙΙGS:

Apple ΙΙGS computer was released in September 15, 1986. It contains new graphic modes having higher resolutions with a palette of 4,096 colors and upto256 colors on the screen. This computer was best suited to displaying the statistic images.

It was the main reason of legacy of the Apple ΙΙGS. The memory capacity of Apple ΙΙGS was 256KB. It contains built-in peripheral ports and a ROM tool box that supported for the Graphical User Interface. The first 50,000 of Apple ΙΙGS computers came with the signature of Steve Wozniak as “Woz Limited Edition”. But they are not functionally different from other computers that are released without signature.

This makes Steve Jobs out from the Lisa project and joined to the Macintosh project. Lisa was the major project at Apple which spent more than 50 million$ for its development. It consists of 1MB of RAM. It was more advanced than Macintosh system that consists of protected memory and cooperative multitasking. It uses two sided 5.25 floppy disk drives each of them having capacity of 871KB. It was more commonly known as ‘Twiggy’.
Lisa 2:

Lisa 2 was released in January 1984. Lisa 2/5 indicates that Lisa 2 bundled with External 5MB or 10MB hard drive. It replaces the Twiggy floppy drive by a single 400K Sony microfloppy. It was much less expensive than the original model. Like the Apple ΙΙ it was an open system. It contains two RAM slots. One was CPU slot and another one was I/O slot. There were three Lisa slots parallel to each other. The final revision of Lisa 2/10, modified and sold as the Macintosh XL.
Macintosh XL:

 
Macintosh XL was the modified version of Apple Lisa. Introduced in January 1,1985. It was shipped with MacWorks XL (An Apple Lisa software program that shipped with Macintosh XL) which allows 64K Macintosh ROM emulation. It had 400K 3.5 floppy drive and internal 10MB hard drive. At the time of release it was also called as “Hackintosh”. Because it was created from unusual components of parts and the Mac OS x was the hacked version of OSx86. In this computer CPU was replaced by a new CPU board with 8MB RAM called the XLerator 18. The main purpose of rebranding the Lisa as a Macintosh XL was the ditch effort of Apple to save the poorly sold Lisa. Despite its relative success Apple would have lost money because of Macintosh XL.
Macintosh:

It was the first mass produced computer with Graphics User Interface introduced in January 24, 1985. It have 128KB built in memory came with keyboard and mouse. It was designed to achieve high graphics performance. It used the Motorola 68000 microprocessor. The boot procedure and Os routines were contained additional 64KB ROM. The 68000 microprocessor had unrestricted access to DRAM which leads to reduce the overall system performance of CPU. This made the machine ran slowly and its competitors have high performance computers than it. Its display was in black & white color that was produced by CRT method with pixel resolution of 512×342 pixels. The software used in this system was System & Finder application known as system 1.0 that includes the Mac Paint, Mac Write applications. This machine was redesigned and released as Macintosh 512K in September. It expanded the memory from 128KB to 512KB. The 128K Macintosh was nicknamed as thin Mac and 512K Macintosh was nicknamed as thick Mac.
Macintosh Plus:

Macintosh Plus was introduced in January 16, 1986 after the Macintosh 512K. It was the third model that in the Macintosh Series. It was the first model that includes SCSI port (Small Computer System Interface, stands for physically connecting and transferring data between computers and peripherals) and SIMMs (Single In-line Memory Modules). In this model 512K memory shipped with 1MB RAM standard and expandable to 4MB. In January 1987 it was transitioned into Apple’s long-lived platinum-gray color. It also included the third party software applications such as MacDraw, Microsoft Word, Excel and PowerPoint, Aldus’s pagemacker.
