Western Digital is one of only three hard drive manufacturers remaining in the computer industry. But their history didn’t start out with making hard drives themselves. Let’s take a look at the history of Western Digital hard drives and what led them from making accessories to making the drives too.
I heard earlier this year that you can retrobright without chemicals, using only sunlight. I haven’t heard of a lot of people trying it. But I had a yellowed disk drive, and it’s summertime, so I decided to give it a shot.
A few people experimented with retrobright without chemicals in 2019, then the idea kind of faded away. I decided to try it, and found it works surprisingly well.
When Commodore introduced its PET line of personal computers in 1977, they needed a bus to connect peripherals. Rather than do something proprietary, they chose an industry standard, the IEEE-488 bus originally designed by HP. It suited Commodore’s needs at the time, even though it’s pretty obscure today.
We don’t typically associate the ginormous 8-inch floppy disks with Commodore. But Commodore produced no fewer than four different models of 8-inch floppy drive for its PET/CBM line of computers.
Unisys was once the second largest computer company in the world, and the name of one of its products, Univac, was briefly synonymous with the word “computer.” It’s no longer the force it once was, but Unisys survives today, in a slimmed-down form.
Unisys still produces computer hardware, including mainframes. But like its rival IBM, it makes most of its money in software, service, and integration.
At least two of the most popular operating systems of today are based on Unix. But what about Windows? Is Windows Unix based?
While Windows has some Unix influences, it is not derived or based on Unix. At some points is has contained a small amount of BSD code but the majority of its design came from other operating systems.
The Atari 800/XL//XE series may be the most underrated 8-bit computer line of the 1970s and 1980s. Yes, I said 1970s, as it debuted in 1979. But while the Atari 800XL is perhaps the most popular machine from that family, and it’s better in most ways than the Atari 800, the 800 has its own advantage too. Let’s look at the Atari 800 vs 800XL.
When troubleshooting machines, I was trained to routinely reseat every board and every chip in the case. Especially if there was nothing visibly wrong with the machine, it was amazing how often that worked. So why does reseating RAM work? Why does reseating anything else work?
Reseating works because it improves conductivity. Connectors can get dirty or oxidized, and if that interferes with conductivity, it causes malfunctions.
Aliexpress offers deals on hard-to-find items at unbeatable prices. It also offers deals on ordinary items at lower prices than usual, because it’s coming straight from China, with fewer middlemen. But is Aliexpress safe?
Aliexpress does offer buyer protections. But being overseas and dealing with overseas shipping times does mean Aliexpress is inherently riskier from buying from online sources that are closer to you.
The Laser 128 computer was an Apple II-compatible home computer manufactured by Video Technologies Ltd in Hong Kong and sold in the 1980s. It was available via mail order and in some retail stores like Sears. In spite of the name, there wasn’t anything optical about it. The name “laser” just sounded like high technology in the 1980s.
Other Apple II clones usually violated Apple’s copyrights, but the Laser 128 did not. It blended some of the features of both the Apple IIe and IIc computers.
