Atari 2600 power supply specs

Dave Farquhar Retro Computing May 30, 2017September 14, 2023amperage, amps, atari, atari 2600, voltage regulator

The Atari 2600 power supply wasn’t as durable as the rest of the Atari 2600, which is nearly bulletproof. By far the most common issue with the Atari 2600 is a dead AC adapter. Fortunately, a suitable Atari 2600 AC adapter isn’t hard to find, even today.

After you replace it with something new, or at least newer, a dead Atari console usually springs right back to life. And if you’re wondering, the same problems apply to Atari 2600 clones like the private-label Sears Video Arcade and the Coleco Gemini and they can also use the same replacement power supplies.

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.

Radio Shack computers

Radio Shack released one of the first home computers, the TRS-80 Model I, in 1977. Between 1977 and 1979, it sold 100,000 units. Radio Shack sold them just as quickly as Tandy could make them. You can count Radio Shack and its parent company Tandy among computer companies that failed, but they enjoyed a good run. For a time, Radio Shack computers, later marketed as Tandy computers, were very popular.

Radio Shack and Tandy computers included the TRS-80 Model I from the inaugural class of 1977, the pioneering Model 100 portable, and the Tandy 1000 series, which helped bring PC clones into homes.

There were several reasons why Radio Shack computers were hard to compete with in the late 1970s and throughout the 1980s.

IBM PS/2 series

The IBM PS/2 line, released April 2, 1987, was IBM’s attempt to reinvigorate its aging personal computer line and fight off cloning. Although the line sold fairly well, it failed to hold off cloning and IBM never regained the market dominance it enjoyed in the first half of the decade.

The IBM PS/2 did offer numerous enhancements over the PC line it replaced, but IBM’s customers came to resent the high price and the perception that IBM was trying to lock out third party peripherals. IBM’s decline was slow, but the PS/2 was the beginning of the end for IBM’s personal computer business.

Why Jack Tramiel left Commodore

Retro computing fans, especially Commodore and Atari enthusiasts, all know the story. Jack Tramiel left Commodore, the company he founded, in early 1984 at the height of its success. Then, within a few months, he gained control of Commodore rival Atari.

But why?

Commodore 64 vs Amiga

Looking at the Commodore 64 vs Amiga seems a little odd, at least to me. After all, the machines were never intended to be rivals. The Amiga was supposed to succeed the 64. Commodore bought Amiga because they couldn’t make a 64 successor on their own, so they intended for the Amiga to replace it. It didn’t fully succeed, and maybe that’s why the comparison is still interesting.

Looking back, the machines may seem similar today. But in 1985 they sure didn’t.

The old Montgomery Ward building in Kansas City

Dave Farquhar Retail November 4, 2016March 9, 20211980s, atari, Kansas City, marathon, matchbox, Meals, Mississippi River, Missouri

I remember the old Montgomery Ward building in Kansas City. I spent plenty of time in the sprawling complex at 6200 St. John Avenue in Kansas City near the intersection of Belmont Boulevard.

When I was growing up, the three most dreaded words in my (and my cousin’s) vocabulary were “Ward’s over town.” That was what our family called the monstrosity, which was home to a regional distribution center, an outlet store, a catalog store, and corporate offices in a mere 2 million square feet.

When we were eight years old, this store was where Saturdays went to die. I don’t know how many of its 2 million square feet were open to my mom, aunt, and grandmother to look for bargains, but there was plenty of room for bargains to hide, and if there was ever anyone willing to spend the whole day in that store stretching a dollar just as far as it could go, it was my aunt.

Irving Gould and Commodore

Irving Gould was a Canadian financier and chairman of Commodore International. Although it’s an oversimplification, journalist Robert X. Cringely dismissed the once high-flying computer company, which had 60% of the market in 1984, as Irving Gould’s stock scam.

Gould was a bit of an odd fit to be running a computer company. He knew finance, but admitted in 1988 that he didn’t know how to use a computer.

Cleaning electrical contacts with Everclear

When I was 19 or 20, I paid a visit to my old grade school to do some computer repair. My fifth-grade teacher dropped in, saw me cleaning up the contacts on a circuit board, and asked why I wasn’t using Everclear. Cleaning electrical contacts with Everclear is, at least, a practice people talk about a lot.

Well, I couldn’t legally buy Everclear yet, for one thing. But let’s talk about why Everclear is good for cleaning electrical contacts but there are other things that can be better.

Commodore 64 vs VIC-20

Dave Farquhar Retro Computing December 7, 2015October 26, 20221541, 1980s, 6502, amiga, atari, atari st, commodore, commodore 64, jack tramiel, Microsoft Basic, MOS, power brick, public domain

How do you compare the Commodore 64 vs VIC-20?

The Commodore 64 and its predecessor, the VIC-20, look a lot alike, and the VIC-20’s design certainly influenced the 64. The 64 is the best selling computer model of all time, and I argue the VIC-20 was the first really successful home computer. The success of the two machines allowed Commodore to surpass Radio Shack as the sales leader in the computer industry. Yes, both Commodore and Radio Shack outsold Apple.

But even though the two machines are closely related, there are significant differences between them. It’s important to remember that in the 1980s, two years was a comparatively long time because the market was moving so fast. Plus, the VIC-20 was always supposed to be an entry-level machine. In 1982, the 64 was supposed to be fairly high-end. Let’s compare and contrast the two venerable machines.
