Digital Equipment Corporation was perhaps the second most important computer company in history, behind IBM. Its minicomputers challenged IBM, and, indeed, Unix first ran on a DEC PDP-7. DEC’s Alpha CPU was one of the few chips to make Intel nervous for its x86 line. It created the first really good Internet search engine. In a just and perfect world, DEC would still be dominating. Instead, it faded away in the 1990s. What happened to Digital Equipment Corporation, or DEC?
Part of being a system administrator is copying large quantities of files around, for any number of reasons. The traditional command line tools for this, Copy and Xcopy, have some limitations. For this reason, two companies extended Xcopy: Microsoft, with Robocopy, and Pixelab, with Xxcopy. Let’s compare Xxcopy vs Robocopy.
CP/M was, as you probably know, the first popular microcomputer operating system. It was good but imperfect, and its cryptic command for copying files, PIP, is often cited as an example. Copy makes sense. Even the Unix equivalent, cp, makes sense–it’s copy without the vowels. But what does PIP mean? What’s the origin of CP/M’s PIP command?
I’m a Royals fan living in St. Louis, so my perspective on Albert Pujols has always been that he’s the one who got away. He went to high school and college in Kansas City, but somehow Royals scouts overlooked him. The Cardinals signed him, and he became a once-in-a-generation player. Even if he never plays another game in the majors, he’s a lock for the Hall of Fame.
Fans loved him, because, well, who doesn’t like a guy who hits .299 with 37 home runs and 99 RBIs in the worst year of his career? He’s always been detached and distant, but St. Louisans will forgive that for wins and numbers. He talked about being a Cardinal for life, but then St. Louis woke up on Thursday morning, drove to work, and found out on the rush-hour radio that he was gone, signed to the Los Angeles California Angels of Anaheim, the Tikki Tikki Tembo Nosa Rembo Chari Bari Ruchi Pip Pen Pembo of baseball.
Veteran tech journalist Dan Tynan recently published a list of 10 overrated technology products, and CP/M was on his list. But was CP/M overrated? I want to dig into that question a bit.
I think everyone knows the story of how IBM almost used CP/M as the operating system for its PC, but ended up using an upstart product from a small company named Microsoft instead. We’ll probably never know exactly what happened, seeing as the author of CP/M is dead and his business partner is no longer able to recollect those events from the 1980 timeframe, and IBM and Bill Gates have no reason to embarrass themselves by revisiting the story.
But CP/M was the first and most popular operating system for early 8-bit computers, so people who used it remember it fondly, and the way Microsoft steamrolled it made Gary Kildall and his operating system folk heroes to underdog lovers everywhere. Even people who never used it and weren’t even born when Kildall’s company ceased to exist have at least a vague idea of what it was. Read more
