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

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 […]

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.

OS X 10.10 Yosemite

Apple previewed OS X 10.10 Yosemite on June 2, 2014, at the Worldwide Developer Conference (WWDC). In addition to a lot of new features and a whole new level of integration with iOS devices, Yosemite looks like the most beautiful version of the Mac OS to date.

The Mac SE Experience, Part 1

I had been on the lookout for another Mac to add to my collection. My wife had led me to believe that if I was so inclined to pick up another, that it should be free or very close to it. I posted some ads on the local buy/sell Facebook groups and even on the […]
