Dawn of the Personal Computer: From Altair to the IBM PC
Atari 400/800
Atari became a household name with their arcade games and built on that reputation with home gaming systems including Pong and the Atari 2600 game console.
It was inevitable, then, that Atari further capitalize on their name by entering the burgeoning home computer market. They did so in 1979 with the introduction of the Atari 800 and its little brother the Atari 400.
The Atari systems were similar to their competitors, the Commodore Pet and Apple ][, in their use of the 6502 processor, but Atari’s gaming roots resulted in the inclusion of several custom chips to control sound and graphics making the Atari 800 an early gaming masterpiece.
This helped sell the machines while various productivity applications such as word processing, database and spreadsheets helped them find a solid following in the home market.

Notable Firsts Atari’s first home computer
Apple ///
The Apple /// represents Apple’s first real failure.
With 128K of RAM, a built-in floppy drive and optional hard drives this Apple was intended to be a true business computer but early design flaws and a high price kept it from success while IBM came in and stole the show.
The machine was sold without a fan which made it overheat causing the main-board to warp. One official Apple solution promoted percussive maintenance to fix the issue - users were advised to drop the machine several inches to re-seat loose RAM chips.
By the time Apple had addressed the early flaws with the introduction of the improved Apple ///+ the PC was the dominant player in the business market and Apple was on the sidelines.

Notable Firsts Apple’s first misstep
Osborne 1
Adam Osborne did lots right when he bundled his computer with all the useful applications—word processing, spreadsheet, database, programming etc.—and sold it for a reasonable price.
He also made computer marketing history when he pre-announced the “Next Big Thing” way too soon and killed the revenue stream he needed to complete development on that next big thing.
The Osborne “luggable” was an evolutionary dead-end (which didn’t prevent dozens of other companies from Compaq to Zorba from copying the form-factor) but it did show that people wanted to be able to take it with them and it proved that hardware was only a means to software.
RAM 64K
CPU 4MHz Z80
Supporting OS CP/M
Predecessor Early CP/M machines
Successor All suitcase portables, later Osborne models
Notable Firsts First suitcase portable, first system bundled with full suite of applications
