back to article Microsoft's MS-DOS is 30 today

MS-DOS is 30 years old today. Well, kind of. On 27 July 1981, Microsoft gave the name MS-DOS to the disk operating system it acquired on that day from Seattle Computer Products (SCP), a hardware company owned and run by a fellow called Rod Brock. SCP developed what it at various times called QDOS and 86-DOS to run on a CPU …

              I believe those pesky ps2 connectors wouldn't allow your keyboard to work after the F1 message appeared. You had to manually reset the PC in order for the keyboard to be operational.

              And the mouse and keyboard connector were the same. I used to work in a helpdesk and the first question I asked customers, when their keyboard and mouse didn't work, was if they recently moved their computer to another location. Some people freaked out and thought I was psychic!

    The last stand-alone version of MS-DOS was 6.22, not 5.0. I know this because I upgraded my 5.0 system to 6.22.

    1. Anonymous Coward

      @Steve the Cynic

      I think what they meant by stand-alone version was that you could buy it off-the-shelf without the requirement of having a DOS (any DOS) present on the hardware. MS-DOS 5.0 shipped as upgrade from MS-DOS 3.3 and as a fresh install, but I am in agreement with you that MS-DOS 6.0 and later 6.2 did ship as both standalone and upgrade version.

      Microsoft offered me MS-DOS 6.2 for free, and then 6.22 too because of the Stac lawsuit that made DoubleSpace in MS-DOS 6.0 illegal... Oh well. :-)

              Punch cards tended to jam if you stuck anything on them. However, splicing paper tape was quite common. I can remember using a device which we called a "micro VAX" - this thing held two ends of paper tape in place while you spliced them together. It came with a little tool with which to manually punch through holes in fresh tape covering a spliced joint.

    The OS for the new IBM PC was always “PC DOS” because “DOS” or “IBM DOS” mnemonic was already taken by DOS later renamed DOS/VSE and lives today as z/VSE.

    That really brings back memories

    For the longest time as a child, I used to view computers as little more than glorified games machines. Oh, I'd sometimes type cheat programs in BASIC on my Amstrad but that's about as far as it got.

    When my dad got his first PC, the pattern continued, with myself just playing a couple of games on it. Then one day I happened upon a tutorial for this weird thing called MS-DOS. It was confusing and terrifying but by the same token, oddly intruiging as well. I began poking around in different directories, learning how to move, copy and delete files using the command prompt. I even progressed to the arcane mysteries of creating custom config.sys and autoexec.bat files.

    I was never blown away by Windows 3.x and only really started using it with the release of Windows 95. But I'll always be grateful to MS-DOS and that tutorial for showing me that there's more to computers than gaming.

      I started with windows 95, and MS-DOS was what you used if you wanted gaming... I learned an incredible amount from poking around in DOS trying to get a game working properly. The joys of owning a 'soundblaster compatible' card instead of the real thing!

        Agreed. The kids today just can't appreciate the pleasure in finding the exact combination of device drivers being loaded (and loaded into UMB) that will suddenly make a game work...

        Privateer was a pain in the neck - for some reason to get the thing to work I'd have to DriveSpace my C:, install the game on the rump bit that isn't compresseed, and then in an optional boot mode choose not to load drivespace - if I didn't drivespace the damn drive it wouldn't work for reasons I could never figure out.

    MS-DOS 5.0 last stand-alone DOS?

    You sure about that? I distinctly recall in 1994 having the option of being MS-DOS 6.0 in Upgrade or standalone form. Because my PC came with MS-DOS 5.0, I opted for the upgrade version, although the upgrade pretty much was like the stand-alone version anyway, because instructions on how to install MS-DOS 6.0 Upgrade on a clean system were included.

    Perhaps it was a specific edition for some markets, but the standalone option definitely existed.

  16. rurwin

    MS-DOS certainly did not die with version 5.0 or with the last retail sale of 6.22

    Microsoft ended OEM licensing of MS-DOS on December 31st 2005. No commercial distribution of MS-DOS was permitted after that date. Existing systems could be serviced but not modified. The XP components could only be used with XP. Since it was so simple, MS-DOS was actually quite useful for embedded systems... just so long as users never needed to look at it.

    Any availability through TechNet will be limited to test purposes.

        TCP/IP on DOS?

        Easily done when using the right drivers. Its even covered by Microsoft themselves, check out this link:

        "18 steps to a TCP/IP bootdisk". I've used this setup a couple of times in the past when I had to quickly backup a run amok PC and decided to use Ghost to make a full disk image before I started messing with it. Clean, small and pretty fast and reliable too.

        Of course; I prefer Windows 7 (and to some extend Vista) these days. The separate boot partition which also contains some fail save utilities is IMO a very big step forward in comparison to XP. A little late, but welcome nevertheless.

    If you're wondering why CP/M-86 didn't make it, take note of the fact that the first file in the screenshot is PIP.CMD.

    On the original CP/M, nearly every command was PIP (short for Peripheral Interchange Program, I believe). For some reason Gary Kildall never seemed to grasp that users might like to use words like "copy". I seem to recall that the arguments were in geeky order, too, so "copy b:" was "pip".

    There was a similar universal PIP command on the DEC operating system RSTS/E - a grown-up o/s that should have been capable of better.

  18. rurwin

    Re: PIP

    Regarding PIP, RSTS was probably where CP/M got the idea from.

    RSTS used a strange method of storing filenames on the disk: it converted the characters to base-50 and then stored three characters in each 16-bit word. I can't remember now if it was six characters in total or six characters plus a three character extension, but that is where CP/M, and hence MS-DOS, got the concept of defining the type of the file with a a three-character suffix separated by a dot.

    1. Anonymous Coward

      RSTS/E - My first program

      While at university, during those surreal 70s;

      I wrote my first program on PDP 11/70 running RSTS/E in BASIC, Then things went backwards a bit punching cards for some ICL OS called GEORGE/3 IIRC. We had an 11/780 before I graduated, but I had moved on to other more intellectual pursuits by then.

      PIP was strange, but generally CPM was always way a way better OS than MS-DOS (OK, directories weren't, but ...). CCPM was really very good, allowing IIRC 4 concurrent sessions for a user. CCPM was released for the DEC Rainbow and DEC sold a zillion (or at least many thousands) to florists, and for a decade afterwards, I would see Rainbows happily running CCPM and operating florist's (and some self-store outfit too) businesses. GEM cam on top of it which again was really quite slick for it's time.

      It always saddened me that the world had MS-DOS foisted upon it, because, as always, there were better alternatives and by the market choosing badly, progress was impeded.

      I though we were on the right track with WinNT which was basically a VMS clone. But MS crippled it with backwards compatibility to Win32S and bolted a hideous windowing system on top of it, brain dead disk nomenclature etc. etc. H

      I still have my copy of DR-DOS 7 on the shelf. I don't have anything to run it on, or any programs to run on it, but one day before I croak, I may boot it on a VM to show my heirs what the PC world was like "when I were a lad".

      I could go on, but I think I will just drink beer instead.

        Rainbow MS-Dos

          MS-DOS on SCP hardware

          DOS on Seattle Computer Products could address over 900K of memory. Tim Paterson mentioned that Microsoft kept a couple of SCP machines around for linking the linker. Since SCP machines were normally used with terminals, there was no need to set aside memory for the display.

        2. Anonymous Coward

          Yes that was an IBM thing

          If I recall correctly, the 8086/8088 chips had an output pin for memory/periphal device mapping so memory and peripheral devices could share the same address space. IBM chose not to use this and went to a purely memory mapped peripheral architecture, putting the peripherals in the address space between 640K and 896K.

          My first computer was a Victor 9000 which came out about 6 months before the IBM PC and blew away the PC on spec's. It could directly address 896K memory. Whereas the PC first had 640x480 pixel text only display, the Victor 9000 had an 800x600 pixel graphic display with 8 shades of green. The IBM PC had 360K single speed floppy drives; the Victor 9000 had variable speed drives that allowed it to pack 1.2Meg on a standard 360K floppy. The Victor was designed from the ground up to be a CAD machine and even had a built-in light-pen interface.

          The Victor was supported by Microsoft all the way up to MS-Dos 2.52 (if memory serve me right), though PC programs could not run on the Victor without an emulator.

          My Victor came with 128K memory which I eventually upgraded to 896K by purchasing a bunch of the indivual memory dip packages and plugging them into the motherboard. (How many are old enough to remember doing memory upgrades that way?)

          Unfortunately Victor was a relatively small calculator company in Europe while IBM was, well, Big Blue, so the PC beat out the Victor and other technically superior offerings, much like has happened with a host of other technologies through the years.

          1. Steve the Cynic

            Pedantry again...

            Actually, IBM *did* use the I/O port space. Just where in memory do you think that, for example, the UARTs (serial ports to you, grasshopper), the parallel port(s), the floppy controller, the PIC, etc. live? Answer: they don't live in the memory space. They live in the I/O port space.

            Even graphics adapters have fingers in the I/O space. It is only the memory window that lives in the memory space, because it is too big (ever since the EGA days, mind) to fit in the I/O space (which is only 64KBytes in total, and the original IBM 5150 only connected the bottom ten bits of the I/O address to the slot connector so ports repeated every 1024 addresses...). The main control interface to the chips lives in I/O space. In fact, the EGA managed to fit its entire 256Kbyte memory into a 64KByte window by fitting 32 bits into every byte of that window.

    Useful stuff

    Well remember using DOS a great deal in the late 80s/early 90s. Even when running Windows you found yourself going into the command line to do stuff like copying and deleting - so much quicker than all that drag'n'drop business.

    Just recently I rediscovered the command line on my Mac - I had a ton of files that needed to be renamed, so rather than going into Finder, i fired up the Terminal and started typing. All done in seconds! Funnily enough, I had tried to delete a file, forgetting it was Unix based, I typed DEL rather than RM. The old DOS never dies!

    I think all wannabe computer students should be forced to use a command line.

    I wish that Seattle Computer Products had copied MP/M rather than CP/M. The biggest issue with MP/M was there was no standard for the needed bank-switching support under the 8080/Z80. However, the 8088/8086 had that built in (the segment registers), so they could have had multitasking from the beginning. Imagine: no Terminate-and-Stay-Resident, no Multiplex Interrupt hacks, multitasking from the beginning. What a wonderful world it would have been.

    Or... Check impossible to understand Windows 7 64bit filenames from OS install. Why are they 8.3? Ask MS.

    The honest ones are not "highly competitive"

    (Announcing features before they're ready for release is) "now a common tactic employed by highly competitive tech companies."

    Meaning, MS and Apple? Anybody else, really?

    Correction on Libel suit

    Tim Paterson "rebuke" by the judge was not due to lack of a case, it doesn't take much digging to demonstrate that QDOS had seriously different internals than CP/M, e.g. INT 21H calls for accessing the API, FAT versus bitmap for managing disks, COPY as a built-in function versus the external PIP, etc.

    The rebuke was that Tim Paterson was supposedly a "public" person and thus had to meet a higher standard for libel than a private person.

    Would that it had never been born.

    A horrible, horrible thing --- that gave rise to something far, far worse that is now a seemingly unassailable monster.

    the article clearly reveals how, even at the start, Microsoft's expertise was in business negotiation and trickery, and not in technology.

    Ultimate backwards compatibility

    Granted; the title doesn't hold truth every time. After all; when Vista and Windows 7 came onto the market the first problem was that many hardware devices were no longer supported. Still; was that really MS' fault or that of the manufacturer which didn't release a new driver? IMO its a combination of both, but alas....

    I lived the DOS days, I also used ramdrives (boot from floppy, then create a ramdrive, copy and set comspec to your ramdrive. Result? You could remove the floppy!), norton commander, windows 1.0 and so on.

    I strongly disagree with comments like "we best forget". Although I agree that many things have changed since then, the very essence has not: trying to get as much out of a system as possible. Whether that is DOS or Windows 7, if you're a techie then this simple fact remains.

    And what I truly respect from Microsoft in this is that Windows remains compatible with older DOS applications, even Windows 7!

    If you use the regular command prompt you can't really do much with it except change its appearance. However; if you go to \windows\system32 and then check the properties of the "" file in there you can even setup properties like XMS and EMS. Some old DOS programs are very picky about those settings, and despite that you can still run these natively within environments like Windows 7.

    IMO you can only respect that. 30 years after date and Microsoft still makes sure that you won't have to throw away programs from that era. In that respect I think they learned a lot from Unix, which basically behaved in the same way (my main example being Solaris here).

      re: backwards compatibility...

      Most of the really old stuff is still compatible, but you can always slap in a DOSBOX, that happens to carry some Linux traits, and run anything DOS-era, including the most picky game you can find, and anything else you can find under the sun that is NOT compatible with 'hosted' DOS.

      And it works 'inside' a Linux box, or a Windows 7 box.

      (I still miss hitting Ctrl-alt-del and geting an actual reboot, instead of another menu, though.)

      Note 1: Can current machines boot in pure DOS? I mean, the latest SATA drives, on the latest BIOS interfaces, are actually capable of booting a bare metal DOS, even if you create a FAT16 2GiB partition? I don't think so.

      Note 2: A Windows 95 game called Fury3 (cube) released by MS herself doesn't even install correclty in Windows 7. It runs straight from forced prompt with severe performance degradation compared to what you could get in Windows 98. No, there is no present support declared for it.

      Note 3: The first generation of force-feedback joysticks made for Windows 95/98 (by MS again) also don't run properly in Windows 7. Yes, I installed a PCI sound card with the MIDI port just to run it, and had no luck. Yes, there are plenty USB joysticks out there, but I spent good money on that joy, and it worked perfectly. Again, no official support. No, DirectX didn't help one bit.

      Apparently, now I can slap a Xbox controller on the PC.

      Not so backwards compatible, then?

      Well, it holds true for DOS stuff, but for Win95/98 stuff...

    Start as you mean to go on...

    So QDOS became MS-DOS. That's a 25% bloat in the name of the product even before MS made any functional changes.

    Ah... the good ol' days

    Only last week I rescued a old PC by making it bootable with a USB floppy, a copy of MS-DOS 6.2 and the wonderful

    What a great wander down nostalgia lane!

    I recall in college that we could copy our dec-20 & dec-10 programs onto a cp/m discette. I did not realise that cp/m was a cousin of RSTS/E

    I also recall using concurrent cp/m? CCP/M on a device called an ICL Quattro - a forerunner of the DRS300 machines, that used CCP/M to drive four terminals on an 8086 machine? Must have been '85 or '86 when i started at the council. The drs300 's were pretty nifty too. Modular and expandable, we used them for running our ICL VME terminal sessions as well as our Wordstar sessions. (ctrl-KD, anyone?)

    We had some 386 machines after that with ms-dos 5 then windows 3 & 3.1

    However, us old-school boys are now dicovering the joys of managing our Active Directory, vSphere and EMC environments using PowerShell. The command line is dead - long live the command line!
