Wozniak recalls role of memory in Apple's early days

IDG News Service - Apple co-founder Steve Wozniak shared memories about memory on Thursday at the Flash Memory Summit in Santa Clara, Calif.

"The biggest decision I made in most of the projects of my life was what memory to use that's the exact right, smallest, simplest, and more importantly, the cheapest there is," Wozniak told the audience in a packed auditorium.

Wozniak is currently the chief scientist at solid-state drive company Fusion-io. In an earlier interview, he opined about why he sees himself as a "purist" when it comes to memory versus spinning disk for storage.

Even the first major commercial product he designed with co-founder Steve Jobs, the Apple II, was defined largely by memory. Facing the problem of how to refresh the characters on the screen fast enough to keep up with a microprocessor that could do a million operations per second, he came up with the idea of devoting some of the computer's dynamic memory to the display, he said.

"I let the memory that was available, the price of the memory, the efficiency of the design, which components I chose, define how fast that computer could work," Wozniak said.

He also used memory to introduce color to the display, remembering lessons from high-school electronics class about color TVs. Spinning four bits of memory at the right rate could produce 16 colors, he realized. That idea came to him one night as he sat at a lab table next to Jobs, who was wire-wrapping one of Wozniak's hardware designs.

Wozniak has always been known as the more geeky of the Apple co-founders, and on Thursday he recalled the contrasts between them all the way from the time they met in high school. The partnership worked out well, especially when they knew how to build their computer but couldn't afford the best memory chips, which came from Intel, Wozniak said. Jobs talked to someone he knew at Intel and got them for free. "I had always been too shy, too embarrassed, to ask for things for free," Wozniak said.

The two Steves also have different senses of humor, Wozniak said. He remembered being excited to meet Jobs, after a high-school friend had said they might get along.

"I want to meet a guy that likes electronics and likes fun, all the time," Wozniak said. "Um, he doesn't like fun that much ... I think, how many times would I see Steve Jobs just rail out in laughter like you would at good comedy, and it's pretty seldom. We did a lot of pranks together. But he wasn't really a laugher at the pranks, he more wanted to find a way to turn it into money," he said.
