Why do we not know who wrote DOS 3?

Seems to me DOS 3 was quite a forward-looking DOS. Its only crime seems to have been lack of direct backwards compatibility with DOS 2.0s, resulting in user revolt. But from what I've read of DOS 3, the file system seems better designed (if somewhat wasteful owing to the use of clusters) than that of DOS 2.0s. So I don't think the author should be too ashamed. It was just bad timing, and the clusters didn't really suit the (then) low-capacity floppies.

I can't edit, but a quick search didn't remind me where I read it. I read a ton of back issues over the last 4 months. Don't quote this as completely accurate, but I want to say It was Bill Wilkinson, and 3 was the fore bearer to what would eventually become DOS XE. Banging my head on where I read it and now its going to bug me...

Dos 3 was basically FAT. It used pretty much the same structure as FAT. Unfortunately, they tried to fit in the FAT into one 128 byte sector (instead of one 512 byte sector, as on the PC), which required them to combine eight sectors into one block. Needlessly wasteful. Other than that, the FMS itself was fine and removed a lot of restrictions Dos 2 had (no free point & note, no extend,read-write-update mode).

If it had backward compatability, really it would have been worse.

 

Supporting both filing systems would mean plenty more uncommon code.

 

Realistically, FAT is a much better filing system than embedding pointers in data and allocation as a bitmap. But you can't just throw out what was essentially a 5 year old standard that practically everyone was using.

 

If they'd have put much of the code under the OS and included legacy 2.x file system support then acceptance might have been better, but then again XL users and 64K ones at that were somewhat a minority probably until 1985 or later.

I don't think this is accurate. Bill Wilkinson was involved with OSS, and was part of the team that developed OS/A+ and later DOS XL, an early command-line operating system for the Atari. DOS XE was an Atari product, and I don't think OSS or Bill Wilkinson was involved.

I may be wrong with the name, but what I read said that whomever had written it was either leaving Atari or had just left Atari. I wish I could remember the details. I thought they went to either OSS or Activision, but OSS makes more sense. I'm going to have to dig that up this weekend. Where did I read that?!? ugh

Bill Wilkinson did develop DOS XE for Atari. I found that in the Atari 8 Bit FAQ. Though thats not where I read the details on DOS 3. What the %^&* book was I reading!?! This is going to bug me all weekend.

 

Excerpt from: http://www.faqs.org/faqs/atari-8-bit/faq/section-64.html

 

"Before its release, DOS XE was widely known as "ADOS." It was developed by Bill Wilkinson for Atari. The DOS XE disk is labeled: DOS XE Master Diskette (DX5090)."

I have not seen anything for DOS 3 yet, but in the book Inside Atari DOS, Bill Wilkinson from OSS describes how they created DOS 2.0S for Atari.

DOS 3 was my first DOS, and I used it almost exclusively through high school and college. I don't understand all the frustration with it, seems to work ok to me. Of course, I only had one floppy drive at the time.

 

I am sure articles written by "experts" of the time had a lot to do with DOS 3 hatred, wasn't a problem for me, although I realize for people who had a large collection of DOS 2 disks it was inconvenient to say the least.

Listen to the Antic podcast interview with Bill. He confirms he wrote it.
