If anything, Apple’s success in getting the Apple II family of computers into elementary schools was a mixed blessing. The education market kept the Apple II line going, prevented DOS PCs from getting a foothold in most elementary schools, but it also kept schools from buying Apple Macs because they couldn’t run all that Apple […]

The personal computing revolution began with the Intel 8080 CPU. This 8-bit CPU was introduced in 1974 at 2 MHz and was the heart of the first kit computer, the MITS Altair 8800. But it was the far less costly 6502 CPU that drove the home computing market.
Personal computing never would have gotten started if not for the invention of microprocessors, which puts a computer’s CPU (central processing unit) on a single chip – sometimes with companion chips. Intel released the first commercial CPU in 1971, and the first 8-bit “home computers” arrived just a few years later.
Back in the early days of personal computing, benchmarks were usually written in BASIC and tweaked for each competing brand of computer and BASIC in use. This article looks at some popular benchmarks from the 8-bit era of home computing.
Prior to the September 1986 introduction of the Apple IIGS, every Apple II computer ran an 8-bit 1 MHz 6502 processor, used 5-1/4″ floppy disks, had a very limited color palette, and sound was nothing to write home about. The Apple IIGS changed all of that.
The Apple II family was known for its expansion options – eight slots for adding capabilities. Inevitably one held a floppy controller, typically one held a parallel printer card, and another might have a serial card for a modem or printer. Some bought Microsoft’s Z-80 SoftCard to run CP/M. But for most users, most slots remained empty.
The Apple II and II Plus had been a runaway success for Apple, establishing it in the home, the school, and, thanks to VisiCalc, the workplace. Even though that was true, these models had some shortcomings that were addressed when the Apple IIe was introduced in January 1983.
Although the Apple 1, introduced in April 1976, had been a big success among the hobbyist crowd, people who didn’t mind assembling their own computer and designing a case for it, it was not part of the ready-to-go personal computer revolution of the late 1970s. That’s where the Apple II comes in.
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, […]
In the late 1980s and early 1990s, computing made a great leap forward with the advent of 16-bit microcomputers like the Macintosh, Commodore Amiga, and Atari ST. The Apple II, introduced in 1978, was a phenomenally successful platform, eventually coming to possess a 20% share of the personal computer market in the US. But by […]
