Gary Kildall and what might have been

I didn’t have time to write everything I wanted to write yesterday, so I’m going to revisit Bill Gates and Gary Kildall today. Bill Gates’ side of the DOS story is relatively well documented in his biographies: Gates referred IBM to Gary Kildall, who for whatever reason was less comfortable working with IBM than Gates was. And there was an airplane involved, though what Kildall was doing in the airplane and why varies. By some accounts he was meeting another client, and by other accounts it was a joyride. IBM in turn came back to Gates, who had a friend of a friend who was cloning CP/M for the 8086, so Microsoft bought the clone for $50,000, cleaned it up a little, and delivered it to IBM while turning a huge profit. Bill Gates became Bill Gates, and Kildall and his company, Digital Research, slowly faded away.

The victors usually get to write the history. I’ve tried several times over the years to find Kildall’s side of the story. I first went looking sometime in 1996 or so, for a feature story about Internet misinformation I wrote for the Columbia Missourian‘s Sunday magazine. For some reason, every five years or so I end up chasing the story down again.

The CP/M-DOS forensics don’t prove much

Dave Farquhar Retro Computing August 7, 2012January 10, 2025atari, Bill Gates, Digital Research, Gary Kildall, Jerry Pournelle, john c dvorak, pc magazine, QDOS

I saw the headline on Slashdot: Forensic evidence trying to prove whether MS-DOS contained code lifted from CP/M. That got my attention, as the connection between MS-DOS and its predecessor, CP/M, is one of the great unsolved mysteries of computing.

Unfortunately, the forensic evidence doesn’t prove a lot.

My favorite Phillipe Kahn story

Dave Farquhar Retro Computing June 2, 2012December 19, 2024altair, Bill Gates, commodore, jack tramiel

I just saw Phillipe Kahn (not Khan) in a Best Bait-n-Switch commercial, introducing himself as the inventor of the camera phone.

But that’s not my favorite Phillipe Kahn story.

Don’t call the war on hackers unwinnable

John C Dvorak asks what war we’re waging on hackers. While war may not be the best choice of words, because it’s not exactly a conventional war, there’s no question there’s something going on, and we’re not winning it right now.

The latest salvo is that someone in China is building a botnet using Macintoshes. Read more

How computer and energy technology don’t relate

Bill Gates says the rapid advance of computers created unreasonable expectations for the advancement of energy technology. The argument makes sense. And while desktop computers did advance very quickly, I think people have a misconception of even how quickly computers developed–which makes it worse, of course. Some people seem to believe the computer was invented by IBM and Microsoft in 1981. Far be it from Gates to lead people to believe otherwise, but the direct ancestors of modern desktop computing date to the early 1970s, and the groundwork for even that dates to the 1940s, at the very latest.

UEFI on ARM illustrates why we still have to watch Microsoft

Dave Farquhar security, Software January 14, 2012March 25, 2025android, apple, Bill Gates, cisco, IOS, Steve Ballmer, UEFI

UEFI is a technology that forces a computer to only load a digitally signed operating system. This has some security benefits, as it makes parts of the operating system unbootable if they become infected, since the viruses won’t be digitally signed by a reputable vendor.

Great idea, right? From a security perspective, absolutely. The more attack vectors for viruses we can eliminate, the better off we’ll be. But Microsoft’s policy on ARM systems shows how it can be abused.

Was CP/M overrated?

Dave Farquhar Retro Computing September 27, 2011October 1, 20181980s, atari, atari st, Bill Gates, commodore, commodore 128, DEC, Gary Kildall, IBM, PIP, unix, vector, windows nt

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.

And now it’s Apple’s turn

It’s been a weird month for technology. And as always, Apple had a way to get people to stop talking about anything else, though it’s not the news Apple wanted do deliver this week. I can only think of one bit of news Apple would want to deliver less.

Steve Jobs is stepping down as CEO. He’s becoming chairman, but perception is everything. Especially with Apple. I don’t think any company in recent memory has leveraged perception the way Apple has.

A snapshot in history of Gates and Microsoft, 1992

Dave Farquhar Software July 5, 2011March 25, 20251990s, altair, Andy Grove, apple, Apple Macintosh, Bill Gates, DEC, Digital Research, IBM, intel, macintosh, Microsoft Office, Paul Allen, Steve Ballmer, windows me, Windows XP

Hard Drive: Bill Gates and the Making of the Microsoft Empire is a 1992 autobiography of Microsoft co-founder Bill Gates. It’s old. But it’s a compelling snapshot of what the industry thought of Gates and Microsoft before Windows 95, before Microsoft Office, and before Internet Explorer. Indeed, it gives an early glimpse into the struggle to bring Windows to market, some of the bad bets Microsoft cast on its early productivity software, and just how close Microsoft came to betting the company on the success of the Apple Macintosh.

If Microsoft’s history were written today, many of these stories would probably be forgotten.
