The Atari 2600 CPU: The MOS 6507

The Atari 2600 CPU was a nondescript MOS 6507 chip. Neither Intel nor Motorola had a CPU chip in the early 1970s that could meet Atari’s price point. MOS Technology didn’t have one either, but they asked Atari what they could afford. Then they made one.

The 6507 is so nondescript, some of them don’t even have the number “6507” anywhere on them.

History of overclocking

Overclocking didn’t start in the 90s, and it wasn’t limited to PCs either. Here’s a history of overclocking from a guy who did it some, and talked to guys who did it a lot in the 80s.

I don’t recommend overclocking, and today Microsoft can prove it’s a bad idea. But overclocking has a long and colorful history. It’s less common than it used to be, perhaps. But it’s not completely extinct.

Commodore was more than a stock scam

Dave Farquhar Retro Computing March 15, 2013October 27, 20171980s, 1990s, amiga, apple, atari, Chuck Peddle, commodore, debts, dell, hp, IBM, intel, irving gould, jack tramiel, stock scam, Texas Instruments, TI

From time to time, I see the phrase “Commodore stock scam” or something similar come up in discussion or in books. Commodore, in case you don’t know, was a high-flying computer company in the 1980s that was literally making computers as quickly as they could sell them while Apple struggled for its survival, and was in the enviable position of being the main supplier of chips for its competitors. Imagine if Intel sold computers at retail next to HP and Dell, while still selling chips to Dell. That was Commodore in 1984. I don’t have 1984 figures, but in 1985, Commodore had 38% of the computer market all to itself. IBM and its clones, combined, had 49%. Apple had 13%.

But a decade later, Commodore had squandered all of that away and was out of business. That’s why Robert X. Cringely sums up Commodore as Irving Gould‘s stock scam, then goes back to writing about Apple.

The real story is more complicated than that. More interesting, too.

Commodore founder Jack Tramiel, the orchestrator of the first line of affordable personal computers, died this weekend at the age of 83.

I don’t know exactly what to think about it, and I’m probably not alone, though it didn’t take long for tributes to pour in. Read more

Steve Jobs and the Commodore PET

There’s a nasty rumor floating around that in Walter Isaacson’s bestselling biography, Steve Jobs, Jobs alleges that Commodore copied the Apple II when making its first computer, 1977’s PET. Here’s the story of Steve Jobs and the Commodore PET.

The book doesn’t come right out and say it, but it insinuates it. I know how the PET came to be, and the PET would have happened whether the Apple II ever existed or not.

The little-known story of Commodore

Dave Farquhar Retro Computing June 9, 2007April 10, 20176502, atari, atari 2600, Chuck Peddle, commodore, intel, irving gould, MOS, motorola, stock scam

So I’m reading On The Edge, a longish book that tries to tell the story of Commodore properly, including the people who made it happen, and the companies it bought along the way.

I’m glad the story got told.
