Weird that for a couple minutes, these paths existed:

* https://github.com/microsoft/MS-DOS/tree/main/v4.0/bin

* https://github.com/microsoft/MS-DOS/tree/main/v4.0/bin/DISK1

* https://github.com/microsoft/MS-DOS/tree/main/v4.0/pdf

But they disappeared as I browsed the repo. I guess they didn't want that part public?

Edit: I knew I wasn't seeing things! Somebody forked it along with those files: https://github.com/OwnedByWuigi/DOS/tree/main/v4.0

They force-pushed the repo to remove an insult towards Tim Patterson in one of the source files.

They changed line 70 of v4.0/src/DOS/STRIN.ASM from [0]:

; Brain-damaged Tim Patterson ignored ^F in case his BIOS did not flush the

to [1]:

[0] https://github.com/OwnedByWuigi/DOS/blob/ffd70f8b4fb77e2e6af...

[1] https://github.com/microsoft/MS-DOS/blob/main/v4.0/src/DOS/S...

If Tim is still around he should PR a change back; I'd not want my name shortened to "TP".
EvanAnderson
He should make a PR to change it back to the correct spelling of his name.
hi-v-rocknroll
Agreed. My initialisms are almost as bad. (Thanks clueless parents!)

From Wikipedia, the free encyclopedia

Tim Paterson (born 1 June 1956) is an American computer programmer, best known for creating 86-DOS, an operating system for the Intel 8086. This system emulated the application programming interface (API) of CP/M, which was created by Gary Kildall. 86-DOS later formed the basis of MS-DOS, the most widely used personal computer operating system in the 1980s.

If this release is for historical research purposes, the release should be pristine including the unsavory bits. Whitewashing of history should never be accepted.

Perhaps this release is not for historical research purposes.
Dalewyn
It is for historial research purposes:

>The MS-DOS v1.25 and v2.0 files were originally shared at the Computer History Museum on March 25th, 2014 and are being (re)published in this repo to make them easier to find, reference-to in external writing and works, and to allow exploration and experimentation for those interested in early PC Operating Systems.

>For historical reference

>The source files in this repo are for historical reference and will be kept static, so please don’t send Pull Requests suggesting any modifications to the source files, but feel free to fork this repo and experiment.

Don't leave us hanging!!

At https://github.com/microsoft/MS-DOS/blob/main/v4.0/src/DOS/S... it used to have Tim Patterson's full name whereas after the force push they abbreviated it to his initials "TP".

I had the repo cloned before the force push and when I went to pull it, this file was the only one that contained a conflict.

Looks like the handiwork of Mark Zbikowski, whose initials adorn every EXE file. https://en.wikipedia.org/wiki/Mark_Zbikowski
farmerbb
Mark is the one that committed today's source release, going off of the "MZ is back" commit message from GitHub user "mzbik".

Ya sorry we're moving stuff around

Thx for clearing the rights and for releasing, Scott. And of course thanks to Microsoft and IBM.

It would be fun at some point down the road to get some of the older code building and running again - particularly '84/'85-vintage Windows & Notes builds. Quite a lot of work, though, not just because of hardware but also likely because of toolchain gaps.

rwl4 OP
Well, thanks for putting this up! It's really a treasure for those of us who used it as our daily driver so many years ago.
Karellen
Why is that, no matter how much you check and proofread your work before you push/publish, you'll always find something obvious you missed 5 minutes after it's gone up?

To change a public branch, or not to change a public branch, that is the question.

Edit: Muphry's law strikes again - s/or to not/or not to/

electroly
They just changed the folder. All of those files are now in https://github.com/microsoft/MS-DOS/tree/main/v4.0-ozzie
willxinc
Looks like they were moved to the Ozzie subfolder: https://github.com/microsoft/MS-DOS/tree/main/v4.0-ozzie

That was literally just added; I have a tab open that doesn't have that folder. This is wild and strangely exciting to see released in real time.
shanselman
Ya we wanted to separate the MS-DOS and MT-DOS stuff, it was confusing as it was
rnd0
I'm not complaining, that's for sure! Thanks for all you're doing.
nullindividual
It is all the MT-DOS content; binaries and docs.
