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 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.

I’ve talked a lot about the advantages and disadvantages of old milestone operating systems. But what were the advantages and disadvantages of Windows NT 3.1? That’s a fair question.

The IBM PS/2 line, released in April 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.
Let’s take a look back at the history, trials and tribulations of the IBM PS/2.

The Epyx Fast Load cartridge, released in 1984, was the first commercially successful Commodore fast load product. Commodore’s 1541 disk drive was much slower than competing disk drives, so fast load cartridges became popular.
While the Epyx product was first, and was very popular, it didn’t have the market to itself for very long.

I hear a lot of questions about the Commodore 64 over and over again. Many of them don’t warrant a single blog post. So here’s a list of Commodore 64 common questions and their answers.
If you want to know when the Commodore 64 came out, how many Commodore 64s sold, who made the Commodore 64, where the Commodore 64 was made, is the Commodore 64 worth anything, are Commodore 64 games worth anything, or if you can still buy a Commodore 64, read on.

The symptom: If you install more than 512 MB of RAM in a system running Windows 9x (that’s any version of Windows 95, 98, 98SE, or ME), you get weird out of memory errors.
The culprit is a bug in Windows 9x’s disk cache. The solution is to limit the cache to use 512MB of memory, or less, which is a good thing to do anyway. Here’s how.

The dark beige/tan Commodore 1541 disk drive is rather well known. The lighter beige, almost white 1541c is more of a curiosity. The drives are closely related, but the difference is more than just the color.

Lotus 1-2-3 was the killer app that made the IBM PC the standard for computers. It wasn’t the first spreadsheet, but it ran on a computer that could easily address more than 64K of memory, it was fast, and relatively bug free. So it was super successful. Today we know it as the thing people used before Excel. So what were the advantages and disadvantages of Lotus 1-2-3?

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.
