Commodore PET and CBM

The Commodore PET 2001 was one of the first three personal computers that came to market in 1977, launching the home computing era along with Tandy/Radio Shack and Apple. Commodore’s entry was unique for having an all-in-one design.

Acorn 8-bit Computers

One of the early “home computers” was hardly known outside of the United Kingdom, but in its home country, Acorn owned the education market. Launched by Cambridge Processor Unit Ltd. (CPU) in January 1979, a little over a year after the Apple II, Commodore PET, and Radio Shack TRS-80 came to market, the Acorn System […]

The Early Days of Computer Retailing

Some of you may remember seeing one of the first personal computers at a Radio Shack store in the latter part of 1977. Although there were three competing “home computer” systems on the market, only the TRS-80 was widely available – it was on display at 3,500 Radio Shack stores throughout the United States!

CPUs: Motorola 6800 and 6809

The personal computing revolution started in 1974 with the 2 MHz Intel 8080, Intel’s first 8-bit CPU capable of addressing 64 KB of memory. (The earlier 8008 from 1972 could only address 16 KB.) But there was a parallel path, a new CPU family that Motorola launched in 1974.

Word Processing and Personal Computers

Believe it or not, word processing predated the personal computer revolution by over a decade. In 1964, IBM combined its Selectric typewriter (1961) with a magnetic tape drive in the IBM MT/ST, making it possible for the first time to edit text without having to retype everything.

Origin of the Apple I and Apple II Computers

The first computer worthy of the name “computer” was produced more than 60 years ago. It was a monstrous machine, covering more than 136 square meters and used 18,000 vacuum tubes (the predecessors to the transistor). It was capable of computing the sum of 5,000 numbers ten digits in length per second. It’s name was ENIAC, […]

The Ill-Fated Apple III

As a computer manufacturer, Apple gets a strangely distorted press. Its position as the only serious commercial competitor to Microsoft guarantees that every move the company makes is documented – and often distorted.

2 Apple Failures: Apple III and Lisa

Realizing that the Apple II would not sustain Apple forever, the Sara project began. The main idea of Sara was to create a more powerful and capable Apple II. It would include 128 KB of RAM, an integrated floppy drive, and a high resolution display – 80 columns wide instead of the Apple II’s 40.
