Apple's first major computer, the Apple II in June 1977, also its predecessor, the Apple I in 1976 was based on a 6502 processor released in 1975 by MOS Technology, and in 1975 the least expensive, fully featured processor on the market.
MOS Technology was a chip-building company that had been joined by designers from Motorola, after Motorola's management had forbidden designers from further work on a low-cost version of its 1974 chip, the Motorola 6800. Famously, the 6502 was seen powering Arnold Schwarzenegger in Terminator 1. It was at the heart of the later BBC Micro that kick-started home computing in the UK, and was a big influence on the ARM chip designs that now power Apple's iPhone, and Google's Android smartphone.
Back in 1977, competition to the Apple were in the form of the Atari video console, basically a games machine, and the Commodore PET, though the PET had delivery problems and was back-ordered for months. And competition to the 6502 was the Zilog Z80, running on

However Steve Wozniak had built the first home computer to actually write characters to an ordinary TV screen. Click here for an interview with Steve about that time. Click here for more background on that NTSC signal — 262½ scan lines (having 341¼ dots per line) using 60hz (i.e. 60 scans per second).
In those days operating systems for microcomputers were called resident monitors and its "Woz Monitor", co-ordinating activity between keyboard, screen, cassette and memory, resided in just 256 bytes of ROM (read-only memory). It also came with his version of Apple Basic on tape. Called Integer Basic, it had no provision for floating point calculations.
Still, 200 boards were produced, and all but 25 sold during their 10 months on the market. Click here to see the Apple I's advertisement in October 1976.
$US2698 48kb (but, initially, still excluding a TV monitor and audio cassette drive)
The Apple II came with a fanless power supply and circuit boards now packaged inside a cool, plastic case, memory-mapped display using 1 KB of RAM, plus a keyboard.|
It now offered the user programmable colour commands inside its version of BASIC that would run on that TV screen, pretty much a first for a home computer.
Later that year Apple added floating point calculations through a deal with Bill Gates, providing the user with a licensed copy of Microsoft Basic, calling it Applesoft Basic.
Note too, these were the days when you bought, loaded and saved data and programs on cassette tapes. It was to be 12 months before either Apple (or Tandy) released a floppy disk drive.
|With strong encouragement from Mike Markkula (formerly from Intel), and to a huge reception in July 1978, Steve Wozniak designed a hardware controller and released the Apple floppy disk drive, the Disk II. The software for it was called Apple DOS consisting of a File Manager, a BASIC interface, and some simple utilities — written by Paul Laughton in just seven weeks April - June. Click here to read his story, also a copy of the Apple II DOS source code. So after July, you could save and read files almost immediately instead of having to sequentially search a cassette tape.|
|1979||Now came VisiCalc, the first Spreadsheet program for microcomputers, released in October 1979. The Apple II was more than just a hobby machine, it was a serious business tool. Though from a wordprocessing viewpoint there was no lower case functionality.|
|March 1980||Microsoft Consumer Products (an end-user/dealer branch for Microsoft) release the Z80-Softcard for $US349, a plug-in board with an 80-column display that came with both the CP/M operating system and Microsoft Basic. Click here for this announcement. CP/M could run Wordstar, first released back in June 1979, a true WYSIWYG (what you see is what you get) word processor supporting upper and lower case characters.
At the same time, Corvus Systems "hack" the Apple DOS software and release a file server for this Apple II supporting 5mb and 10mb (and in 1982 20mb) hard drives. It became very popular in primary and secondary education — via this single drive and backup a full classroom of Apple II computers could be networked together.
In Mt Gravatt Qld, the Zardax word processor (for a 40-column upper and lower case display) was written and released by Computerland Australia, easy to use, and very popular.
Development of the Apple III had started in late 1978 to address weaknesses that the "business" market saw in the Apple II. It was released in May 1980, supporting an 80-column display with upper and lower case characters and a built in floppy disk drive. It was expensive though equivalent to about $US12,600 in 2016 dollars, and there were serious stability issues in the logic boards.
Following a design overhaul, it was formally reintroduced in September 1981 along with a 5mb Apple Profile hard drive (costing $US3500). It was still an 8 bit CPU, and was now following IBM's 16 bit Personal Computer (launched in August that year). And it had no "Prt Scn" key, a most useful introduction on the IBM.
|Work on the Apple Lisa also began in late 1978, and with changes of project leadership, Apple spent more than $US50 million and four years developing its graphical user interface, use of a mouse, and running on Motorola 68000's 32 bit processor with 16 bit data bus. After Steve Jobs was diverted over to the Macintosh project in 1982, it was launched in January 1983 with two built in floppy disk drives and 1mb of RAM. But with an introductory price that was close to $US10,000 (that's about $US24,000 in 2016 dollars), again it was, commercially, a failure. Apparently its biggest customer, NASA, used LisaProject for project management and was faced with significant problems when the Lisa was discontinued.

|And next the Apple Macintosh (Motorola Advanced Computer System on Silicon) with a relatively low introductory price, under-configured memory (initially 128KB, it was reconfigured in October with 512KB), but finally a limited success. Had simple networking with a $US50 box (LocalTalk).|
In March 1985 "Print Screen" (Cmd-Shift-4) also "Capture Screen" (Cmd-Shift-3) added.

|1991||NeXTSTEP and the WorldWideWeb|
In 1985 Steve Jobs has a falling out with his board and departs. Launches the NeXT computer running the UNIX-based NeXTSTEP operating system in 1988 (for $US6500), followed by the NeXTcube (for $US10,000) in 1990. Expensive machines, they both sold in low numbers, mostly to universities, financial institutions, and government agencies. But one of the purchasers was the world wide web instigator,
