Over the course of its 12 years on the market, Commodore released a number of Commodore 64 models. The computer’s capability changed very little over time, but the technology did. The world changed a lot between 1982 and 1994, and that gave Commodore some opportunities to lower costs, chase other market segments, or both.

Here’s an overview of the various Commodore 64 models that hit the market over the machine’s long life.

IBM PS/2 series

Dave Farquhar Retro Computing May 17, 2017September 30, 20231980s, 1990s, amiga, atari, atari st, compaq, dell, hp, IBM, infoworld, intel, macintosh, Personal Computer, Tandy, VGA, XT

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.

IT jobs shortage? Slide over to security

Dave Farquhar security September 8, 2014November 20, 2018CISO, cissp, information security, infoworld, Internet Storm Center, job description, Liquid Matrix, Patch Tuesday, podcast, table of contents

IT jobs are getting scarce again, and I believe it. I don’t have a cure but I have a suggestion: Specialize. Specifically, specialize in security.

Why? Turnover. Turnover in my department is rampant, because other companies offer my coworkers more money, a promotion, or something tangible to come work for them. I asked our CISO point blank if he’s worried. He said unemployment in security is 0.6 percent, so this is normal. What we have to do is develop security people, because there aren’t enough of them.

I made that transition, largely by accident, so I’ll offer some advice. Read more

Longtime reader Dan Bowman–probably my very first reader, come to think of it–sent in this article from Infoworld regarding SSDs and data loss in power failure.

It’s not theoretical. I’ve seen it. I also know how to prevent it.

If you needed another reminder to secure your wi-fi…

Dave Farquhar Uncategorized August 13, 2012August 12, 2012infoworld, wi-fi

And if you needed another reminder of why you should secure your wi-fi:

“There’s a very common belief that if someone pirates your Wi-Fi connection or uses your computer without your permission, you are responsible for illegal downloads of copyrighted material. That’s not true, says Stoltz; the law is quite clear. However, the lawyers who bring those cases use that misperception to convince innocent people that they had better pay up. Since $3,500 is just a fraction of the money it would take to fight a case in court, most people simply settle.” —Infoworld

Android modding gets just a little more mainstream

Dave Farquhar Hardware July 20, 2011android, cyanogenmod, infoworld, motorola, pentium ii, Windows XP, XT

Infoworld published a piece on using Cyanogenmod to upgrade an orphan Android phone, the Motorola Cliq XT, beyond the officially supported Android 1.4.

It’s not a detailed how-to and has a lot of generalities, and someone wanting to do the same thing will still have to do a lot of Google searching, but we’re talking a short-ish (I’m guessing 1,500 words or less) Infoworld piece here. It’s a magazine that’s always been more about trends than details.

Nonstandard configuration on a vintage PC? Maybe it was gray market

Dave Farquhar Retro Computing April 17, 2011March 26, 20241980s, 1990s, acer, DEC, dell, IBM, infoworld, markup, Michael Dell, New York, Packard Bell, vintage computer, XT

I saw an interesting question about the configuration of mid-1980s (pre-PS/2) IBM PCs on a vintage computer forum this week. The question regarded how various machines came from the factory, especially when some collectors have PCs they bought from the original owners, including an invoice, showing the machine didn’t match known factory configurations. This made me think of the gray market.

The gray market referred to the practice of discounters getting genuine IBM PCs and reselling them, sometimes modified. The most famous gray marketer was Michael Dell–the “Dell” in Dell Computer Corporation–who got his start by upgrading bare-bones IBM PCs and selling them out of his dorm room and later, out of a condo. Eventually he decided he wanted a steadier supply, and started manufacturing, becoming the company we know today.

But Dell was far from the only one. Read more
