    There is real MS-DOS 4.00 i not talk about multitasking MS-DOS 4.0 is online.
    Is version MS-DOS 4.00 called MS-DOS 4.0 Sampo Oem date 8-3-1988.
    There was post be 6 disks in MS-DOS 4.00 Sampo Oem but there was 5 disk also make setup MS-DOS 4.00 incomplete without disk number 6. Website called Old-Dos.Ru restore original MS-DOS 4.0 Sampo Oem. MS-DOS 4.00 Sampo Oem is complete. To Setup MS-DOS 4.00 go to Disk 1 type Select(Setup) Setup ask you create Select Copy(Blank Disk). After that Setup want Install Disk is Disk 5 and Dosshell is Disk 6 now Setup Complete. After Setup it will boot to DOSSHELL.

    This is download link for complete MS-DOS 4.00 Sampo OEM

  3. dosfan says:

    WinWorld may have some of that software, for example Microsoft C 5.0 is here:

    I suggest adding multitasking MS-DOS 4.10 to the list.

  4. Michal Necasek says:

    That’s unfortunately an incomplete archive of MS C 5.0 (but right now I can’t even download it to check).

  5. Louis Ohland says:

    Looking for a copy of “SurePath Bios Manual document S68X- 2341-02 IBM 1992 ”

    which is the flash BIOS used on the late “PS/2” systems. FAIK, it was an IBM-Phoenix effort. I checked the Internet Archive http://www.surepath.ibm.com, got four? utilities, and that was it.

  6. dosfan says:

    S68X-2341 is the book number for the IBM Personal System/2 and Personal Computer BIOS Interface Technical Reference. The last version I have is from September 1991 and that does not mention anything about the SurePath BIOS.

    SurePath was a joint IBM-Phoenix development but I believe it started in 1993. The IBM PC Series computers (circa 1995) which came after the PS/2 and ValuePoint systems used the SurePath BIOS.

    Just stumbled on this blog today. Thanks so much for making this and maintaining it. I’m in my 20’s at Oracle and really have a passion for computer history / tech history / tech business history.

    I actually have a copy of Solaris 7 at my desk at work, but I’m almost positive it’s for SPARC though. That being said I found it at this place when I was out in San Francisco (I don’t live anywhere near there): http://www.weirdstuff.com/. I don’t think their online inventory reflects their physical inventory as they must have had 100-200 boxes of Solaris…

  8. Michal Necasek says:

    I know of Weirdstuff, although I still haven’t managed to visit their Sunnyvale store.

  9. Nathan Saunders says:

    i am looking to get a copy of o.s. 2 warp 4 can you help?

  10. Michal Necasek says:

    No, sorry… I’d suggest Google and/or eBay depending on what exactly you need.

  11. Kevin G. Rhoads says:

    Helo Michal,

    I have a complete
    Microsoft Programmer’s Library 1.1a
    w/ CD and paper.

    Re DOS 3.20 vs. 3.21 — IIRC 3.20 *tried* to do parameterized floppy support (as was done in 3.30) but it was flaky. 3.21 removed that in addition to other minor changes.

  12. Ken Blair says:

    Wow! I found your site while researching my collection of Intel 386, 486, and Overdrive chips. Your posts are very well written and packed with fantastic information. Thanks for putting this site together. Unfortunately I don’t have any of the items you’re looking for although I have an IBM-branded box for 3.5″ floppy disks. The disks inside are probably a random assortment of whatever.

  13. Michal Necasek says:

    Thank you for the kind words! Check those floppies if you can, there’s probably nothing too interesting but you never know.

  14. Michal Necasek says:

    Hi Kevin, I sent you an e-mail a while ago but I wonder if it landed in your spam folder…

  15. Mike Dunn says:

    Wow, I, as others, just found this site. Man, it has been a while since I’ve read OS/2 dialog. I was on the OS/2 kernel team (small team) and implemented threads and debugger support among other things. Crazy hours. I left in 1987 just before the first release.

  16. Michal Necasek says:

    Senior Software Engineer at Microsoft, I see. You guys must have been one of the first to implement threading, I’d say certainly the first in a mass-market OS.

    And debuggers are so, so, so useful 🙂

  17. Michaaaaal, help !

    Have some old files that were ZipStreamed. I *know* that they had a DOS utility to unzip them. But OS/2 software (along with everything else that used to be on ftp sites worldwide) has disappeared !

    Would you have a clue as to where one might find this antique but necessary utility ?

    Besides that, how’s the world treating you ? I’ve been Irixxing for the past twenty years, maybe I’m a jinx 🙂 But both OS/2 and Irix kick butt over anything available today. Including OS X !!

    Maybe I should get a mac mini and install Warp 3 on it …..

  18. Michal Necasek says:

    Sent you an e-mail a couple of days ago. Please check your spam folder if you didn’t get it.

    Nathan Saunders,

    If you still need help, try looking here: https://winworldpc.com/product/os-2-warp-4/os-2-warp-40

  20. os2vet says:

    Not exactly on your wanted list, but this project might be of interest for you: https://www.patreon.com/posts/project-2ine-16513790 (I am in now way affiliated with it but just came across it)

  21. Michal Necasek says:

    It’s interesting, and I have heard of it, unfortunately a Windows-hosted version would be a lot more interesting to me.
