Exploring The Hidden Roots of MS-DOS: 86-DOS 0.11 (1980)

- If you are familiar with the IBM PC, you'll probably know that MS-DOS was based on a product called 86-DOS from Seattle Computer
Here is one of the earliest builds of what became Microsoft's darling.
It's been compiled in July 1980, and less than 10 people had seen it.
Until now.
Thanks for watching!

The v.10 code is very bare-bones and the file system is a pre-FAT design with shorter directory entries and with no real time clock support yet (notice no date/time in the directory listing). Total system size is about 6.5k give or take.
Beautiful.
Ex-assembler/binary coder (assemblers missed code) on many systems, including writing programs that loaded FAT's (int21).
So much of life has been lost, as the kids today are not presented with a command line, it forced you to learn about computers in the post punch card era. I believe I saw some punch cards but never had the privilege.
Simply beautiful to see an early DOS system, credit to the programmers, you really are hero's to an entire generation or two.

And this was based on CP/M from 1974 which was based on TOPS-10 from 1970 which was based on the PDP-6 monitor software from 1967, right?
So the design origins can be traced far back, like Linux is based on Unix which is based on Multics (1964)...
(By based I mean design choices like API and commands; I know these are complete rewrites and don't share source code, contrary to MS-DOS and 86-DOS)
Things like this are fascinating when they had been the start of pretty much everything today
When I was in high school, for my personal computer all I had was DOS 3.11 and EDLIN, with a dot matrix printer. Wrote entire book reports with that.
Did Someone managed to install windows On the school computers
@@victoriamitchell413 oh they had a computer lab with Windows but my comment was about my personal computer at home. I accidentally erased the disk with a better word processor.
The start of modern computers.
DR-DOS, MS-DOS, Windows, OS/2, maybe even MacOS wouldn't have existed without 86-DOS.
MS-DOS then faded in 2001.
But deep inside Windows,
there are legacy components.
And I bet
that
parts of this version,
this OS,
are in
Windows 11
today.
windows would have existed, but later
os/2 would also have existed
and no, there are no dos remnants, even though there is 31 year old code deep below
no
There's no DOS remnants, since modern Windows is built on Windows NT (NT3.x, NT4, Windows 2000, XP, ...), not the DOS-Based Windows (1.x, 2.x, 3.x, 95, 98, and ME). However there is a load of DOS backwards-compatibility, since 9x is DOS but with 32-bit/16-bit hybrid and a much larger API.
would be intresting alternative history where windows was based on MS-Unix instead of MS-DOS (surely licensing would be problem tho)
@@netkv modern windows is based on os/2
The music is deep & emotional 😊❤
The music makes me feel like there's some sort of human epoch occurring outside and yet I'm sitting here trying to figure out why a seeborg bot from 2004 won't make (it was a hard path in the .cpp file because ofc it was)
Wow...this was NOT on my radar previously, but when I saw this article/video posted in ClassicCMP Discord server, I had to check it out. EXCELLENT archival and documentation work, and thanks for making this available to all! You are a true vintage computer enthusiast!
Form bare bone command line interface to today's OS's flooded with bloatware. . ..

NEW RESPONSE JUST DROPPED
I guess writing a checkers simulation was too hard.
Good alternative to Win 11
The first windows version.
Hello Netdev, could you please share more details about your SIMH, how you start it and the steps to start the 86-DOS. Thank you
Could someone please help me get this working either in Vmware or the tools shown in the video. B just gives me "too few arguments".
yo, do you have vmware inf on windows betas? please!!!
Thanks so much for sharing this!
Hi NTdev
I'm Have Question Can Be Boot windows 8 Or Even Windows 11 On DDR400/300 (DDR1 Ram)?
I don't agree with the title of the video. Ms-Dos is not the root of today pc programs. Don't waste your comments because whatever you may say against it.
Uh...MS-DOS was the foundation stone for Windows 1.0, 2.0, and 3.0, 3.1 and everything Windows related was based on those operating systems, what's wrong with the title? The title is "Exploring The Hidden Roots of MS-DOS: 86-DOS 0.11 (1980)"...was the title some else when you wrote this comment?
While minimal code, if any, is shared with modern Windows, DOS is the origin of the directory structure and device names.
@@VectraQS I can agree on the code, but you still have CMD and I would guess that can you still run many DOS batch files from yesteryear on modern Windows. I still use DIR, REN, DELETE and CD in my day job.
@@adamleinss My batch files written in the 1990s ran in Windows 8. Have not tried them in Win 10 since retirement in 2019. Batches were the first "programming" I learned in the mid-1980s, unstructured as it was with the GOTO (anathema in structured programming). Will spare you the GOTO stories re: their prevalence in legacy code from that era.
I remember back in the days, when you needed to run a executable file (*.com, *.exe or *.bat) you had to type the whole file name with extension. The only moment it was not necessary to type it with extension when those executable files were on path=\
Bro plz reply tiny 11 is safe
