1.4 GHz iMac: What Is Apple Thinking?

We’ve published our first article on the Mid 2014 21.5″ iMac with its 1.4 GHz low-power dual-core i5 CPU, and Chris Carson was not impressed with its value. I want to treat is as fairly and unemotionally as possible, so let’s take a closer look.

LibreOffice: A Free Alternative to Microsoft Office and AppleWorks

LibreOffice is a free alternative to the not-inexpensive Microsoft Office suite. I’m using it to replace AppleWorks, which I’ve been using since ClarisWorks 1.0 shipped back in the System 7.0 era. Unfortunately, AppleWorks is incompatible with OS X 10.7 Lion and later, so I’ve had to find an alternative since installing OS X 10.9 Mavericks […]

Best Android Weather Apps

As Low End Android’s new writer, I figure I should introduce myself. My name is Zach Elliott, and I’ve been a Low End Mac viewer since 2006 when I started collecting vintage Macs while in high school. After I graduated, I attended the University of Oklahoma and graduated in May 2013 with a Bachelors of […]

Can I Run OS X Lion If I Upgrade My Core Duo’s CPU?

Apple’s first generation of Intel-based Macs (not counting the pro-oriented 2006 Mac Pro and Xservv), is build around Intel’s first generation Core technology. Except for the seriously underpowered Core Solo Mac mini, they all use the Core Duo CPU and are thus unable to run the OS X 10.7 Lion installer – or anything newer. In fact, Apple won’t […]

CPUs: Motorola 68040

The Quadra 700 and 900 introduced the 68040 in 1991. In great part due to a much larger L1 cache (4 KB for data and 4 KB for instructions vs. 256 bytes in the 68030) and parts of the CPU running at twice clock speed, the 68040 provides 2.5-3 times the performance of the 68030 at […]

CPUs: Motorola 68030

Apple introduced the Mac IIx, which has a 16 MHz 68030 CPU, in September 1988. The 68030 incorporates the memory management unit (MMU), which was a separate chip for the 68020, giving the ‘030 the ability to use virtual memory (VM) with third-party software, although Apple didn’t include VM as part of the Mac OS until System 7 in […]

CPUs: Motorola 68020

Apple took a big step when it introduced the 68020-based Mac II in March 1987. The new computer was modular, not an all-in-one design like the first four Macs. In addition to 6 expansion slots, a huge power supply, color support, and room for two floppy drives and an internal hard drive, the Mac II runs its […]

CPUs: Motorola 68000

The earliest personal computers used 8-bitCPUs (central processing units). Apple, Commodore, Rockwell, and Atari designed their computers around the MOS Tech 6502; Radio Shack’s Color Computer used the Motorola 6809; and most others, including the Radio ShackTRS-80 and all CP/M computers, used the Zilog Z-80 or Intel 8080. All ran in the 1-4 MHz range and […]

Half a Lifetime with Macs

It’s my birthday, and I realized I’ve been using Macs for half my life. I was 28 years old when I first used a Mac Plus way back in 1986, along with PageMaker 1.0 and the original LaserWriter printer. And 28 years later, I know a lot more about Macs – and myself.

CPUs: Intel Pentium

Intel chose Pentium as the name for its next generation CPU, avoiding the expected 80586 designation – because numbers cannot be trademarked, but names can. The Pentium originally shipped at 60 and 66 MHz in 1993 and eventually reached speeds as high as 200 MHz in 1995. It has 3.1 million transistors using 0.8 micron technology at the […]

The Mac SE Experience, Part 2

This is part two of an epic saga about one man and his Macintosh SE. If you missed the first part or maybe you just need to get a quick refresh about part one, feel free to go back and enjoy it again.

CPUs: Intel 80486

From the 8080 through the 80386, CPUs gained most of its improved performance from greater clock speed and a wider data bus. With the next generation, released in 1989 and 1990 respectively, both Intel and Motorola (in their 680×0 family) worked on making their processors more efficient.

CPUs: Intel 80386 and 80386SX

The 80386 initially shipped at 16 MHz with sample quantities in October 1985 and release to manufacture in early 1986. At 16 MHz, it has a higher clock speed than any Intel version of the 80286. Although the ‘386 includes the same addressing modes as the 8086 and ‘286, it also included new addressing modes, including one […]

CPUs: Intel 80286

Intel’s 80286 CPU, introduced in February 1984, was the first big step forward from the 8088 CPU used in the original IBM PC and a host of PC compatibles.

CGI Story: The Development of Computer Generated Imaging

Alex Schure founded the New York Institute of Technology (NYIT) in 1955 to take advantage of the wave of students studying under the GI Bill. NYIT was initially a correspondence school awarding technical certificates. It distinguished itself from the other technical schools by sending graduates a mess of electronics parts supposedly taken from Soviet warehouses […]

CPUs: Intel 8086 and 8088

The IBM PC of August 1981 was build around Intel’s 8088 processor, a CPU released over two years earlier in June 1979. The 8088 itself was designed as a version of Intel’s 16-bit 8086, but on an 8-bit bus instead of a 16-bit bus. Although this made the 8088 a bit less efficient than the 8086, it […]

CPUs: Intel 8080 and Zilog Z-80

Although the Intel 8080 never ran MS-DOS, it is the direct predecessor of the 8086 and 8088 CPUs used in the first IBM PC. The 2 MHz 8080 was released on April 1, 1974 and formed the core of the first personal computers, the MITS Altair 8800 and the IMSAI 8080.
