This is what a revolutionary technology looks like. In very early 1986 Tim Jenison, founder of NewTek, began distributing these full-color digitized photographs, the first of their kind ever to be seen on a PC screen, to Amiga public-domain software exchanges. The age of multimedia computing had arrived. The Amiga was the damnedest computer. A riddle wrapped in a mystery inside an enigma, then all crammed into a plastic case; that was the Amiga. I wrote a book about the thing, and I’m still not sure I can make sense of all of its complications and contradictions. The Amiga was a great computer when it made its debut in 1985, better by far than anything else on the market. At its heart was the wonderchip of the era, the Motorola 68000, the same CPU found in the Apple Macintosh and the Atari ST. But what made the Amiga special was the stuff found around the 68000: three custom chips with the unforgettable names of Paula, Denise, and Agnus. Together they gave the Amiga the best graphics and sound in the industry by a veritable order of magnitude. And by relieving the 68000 of a huge chunk of the burden for generating graphics and sound as well as performing many other tasks, such as disk access, they let the Amiga dazzle while also running rings around the competition in real-world performance by virtually any test you cared to name. It all added up not just to incremental improvement but rather to that rarest thing in any field of endeavor: a generational leap.
