Former Microsoft Developer Would Like To See MS-DOS Open Sourced

For over an hour on Saturday, retired Microsoft OS developer David Plummer answered questions from his viewers on YouTube.

He began with an update on a project to test the performance of the same algorithm using 30 different programming languages, and soon tells the story of how he was inspired to apply for his first job at Microsoft after reading Hard Drive: Bill Gates and the Making of the Microsoft Empire.

I decided that this is where I wanted to work, because these guys sound like me, they act like me, they are what I want to be when I grow up. And holy cow, they pay them well, apparently. So I wrote to everybody that I could find that had a Microsoft email address, which was about four people, because I had a software product people had been regisering on the Amiga. And one guy, Alistair Banks... responded and he hooked me up with a hiring manager directly in Windows that had an open slot that was hiring... And a couple of interview slots later, I wound up as an intern at MS-DOS working for Ben Slivka.
So you would think, 'Oh, an intern on MS-DOS. What'd you do? Format disks?' No — it's amazing to me, actually. They give you as much work as they believe that you are capable of, and — they get you for all that you're worth, basically. They had me write a bunch of major features, like the Smart Drive cache for CD-ROMs was the first thing I wrote. Then I wrote DISKCOPY, making it work, single pass, bunch of features in MS-DOS. I re-wrote Setup to work on a single floppy disk by using deltas and patching in place, DOS 5 to turn it into DOS 6, something like, or maybe it was DOS 6 into 6.2... A whole bunch of features, within the span of, like, three months, which to me was fairly impressive at the time, I thought. And that only got me an interview...

Later he says that he'd like to see most of 16-bit Windows and all of MS-DOS open sourced, along with some select application code from that era.

I don't think there's any reason to hold back any of MS-DOS at this point. They have absolutely no reason to open source any of it, really — other than PR, because all it brings them is potential liability, complaints and angst, and probably nothing positive for putting the code out there and exposing it to ridicule. Because it's ancient code at this point. It's like, 'Ha! Look what Microsoft did!' Well, yeah, I know Linux is cool now, but go look at Linux code from 1991 — and I worked on some of that code. Well, '93 I did. It's not the same as what you see today.

So yeah, MS-DOS probably looks archaic — although it's super tight, it doesn't have many bugs. It's just written differently than you would write code today, because you're targetting something that is a very different CPU and memory system and PC as a whole, and it's so much more limited that everybody's sacred, every cycle matters. That kind of thing that you don't worry about now. But I'd still like to see all the code from back then that's not embarrassing released.

And when asked what he misses most about being a Microsoft developer, he answers:
I miss going for lunch with the people that I went for lunch with, and talking to the people that I worked with. Because they were a lot like me, they had similar interests, they had similar abilities, they were people like me. We went for lunch, we ate food, it was awesome, and then we talked about cool things. And we did that every day. And now I don't get to do that any more. I get to do it rarely, because I take guys out for lunch and stuff, but it's not the same. So that's really what I miss.

And I miss somebody always feeding me something interesting to do. Because now I have to go out and find something that's interesting to do on my own. And I can't make everything be monetarily remunerative...
