    i have been experimenting with microsoft virtual pc 2004
    the only draw back has been reduced networking speed.

    MSDOS networks just fine. We used to use DeskView alot with MSDOS
    to run in a 'window' type environment. I still have the QuickBasic
    DeskView API which allowed programs to 'see' each other within
    the deskView environment. You could do cool stuff like copy and
    paste from one app to another.

    I've not used DrDos to any extent. It may be easier to implement
    what you want than with MSDos.

    People might argue with me, but IBM's OS/2 has a WONDERFUL
    incantation of DOS in a very beautiful network implementation.
    The learning curve to manage the installation, plus all that
    goes with it is relatively steep, compared to other operating
    systems venues, in my view, but the final product in respect to
    DOS is absolutely superb for use with PowerBasic 3.5. For this
    purpose, I think you'll see server uptimes in the realm of years
    without failure.

    I have at a reasonable number of sites.

    You'll also get a relatively clean and, at this point, really
    free IP connectivity, which is free from most evil things now in
    vogue. That's not because it can't be pranged, but more from
    lack of interest in doing so. As well decent virus protection
    tools are available for you at about the same price as WIN tools
    in the paid-for realm there.

    Importantly, you can also run any variation of WIN on it in a
    hosted mode as a guest. The original tool for this from VMware
    wasn't then finished to release from Beta, but the Connectix product
    which was bought out by M/S does a nice job, although it is no
    longer, at this point, available from M/S with OS/2 as a host
    and WIN as guests. Per what has been told, they'll only sell it
    as a tool to run other things under WIN now..

    However, Citrix, VMware, and significantly, Ecomstation are still
    there and Ecomstation is in Beta now on a replacement for the OS/2
    host operating system variation if you want that. Who cares if you
    blow up WIN every day this way? Just restore the whole partition
    from tape and start all over, chuckle.

    OS/2 is absolutely supported through 4Q 2006 as can be found on
    the IBM sites. Not only is heritage hardware supported far better
    in my opinion, by OS/2 than some other op system choices you might
    make, but you'll get a really decently supported heritage back
    into the 70's for what will run on it. And to find that sort of
    heritage support guaranteed into the future is awesome, as I see it,
    for where we are headed! At the same time a really good array of
    USB, very large hard disk, and other hardware drivers is there.

    The biggest problem is learning where to get at it, and the manual
    work it takes to get there. I also think most people would agree that
    raw installation and auto-sniffing of the most current driver needs
    still isn't one of OS/2's strong points. Too, out-of-the-box ability
    to take advantage of the latest in picture-tools, DVD recording stuff
    and thins like that is going to take you some learning to smooth
    out. But virtually anything you want to do can be done with it,
    except mingle WIN direct operations. And that is getting better and
    better with cross-platform assistance tools from Odin and really
    decent free-ware C/C++ compilers in the form of both Watcom and GCC
    as well.

    Missing, sigh, is the one thing really needed for it, Basic, which
    really would help the issue, if ... sigh. But if DOS is of use in
    this discussion, you can run a dozen simultaneous applications of PB
    all on one box in separate sessions, no problem. As well if it gets
    too bad you can always step up to full symetric multi-processing with
    THREAD orchestration between the CPU's, and not processs limitations
    there. The box I am posting this on has over 40 fully server based
    processes running now as this is written, several DOS/PB applications
    running there and over 700 open files on it as such at this moment. My
    telecommunications remote site box has not been re-booted in several
    months now; DOS, WIN, OS/2 apps, who cares? Plus OS/2 can actually be
    used as an embedded system in a VERY lean boot run, to a complete command
    line with nothing but command line full DOS and OS/2 sessions if that
    is what your little heart is driving for. Mission critical service.


    An Ebay copy of Warp 4 or for the few bux that costs wherever, should
    be your minimal starting point for this adventure. It's like anything
    else in this computer technoworld. You really need the latest fixes
    to keep up with whatever. But there are virtually all cumilative.
    So you'll not wast much time sequentially building on whatever. Free
    support for OS/2 ended a few years back. But updating Warp 4 to the
    current 4.52 common kerneled MCP2 with the current XRC004 Fix Pack for
    it, all the latest TCP/IP and MPTN cumulative fix packs, and the whole
    Mozzilla 1.7 (IBM Web Browser 1.6) game is only going to cost you about
    $65 for a year's support from IBM, with a fair amount of work to get
    them to sell it to you, grin!

    An alternative is to spend about $75 with Ecomstation for their different
    installer and service support for OS/2 with licensing for that year or
    so. Each way to go about this has advantages and disadvantages. But
    if you are unhappy with spending that little money for this horrible
    stable and clean development platform, I suspect little would make you
    happy with how to really bridge the past with the future.

    Yes, we will see changes as the future rapidly brings them to us. But if
    you are looking for mission critical stability in DOS, spanning all the
    way from the 70's into tomorrow for at least a few years of even what
    that brings for needed drivers, I'd carefully consider OS/2 as your DOS
    development and networking platform. It is a marvelous technical item
    when you stop and look both back at the past and into the future.

    Again, it's not a trip for the faint of heart. About two years ago IBM
    officially noted that of the over 80 Billion of revenue world-wide,
    only some 1500-odd customers accounted for over 90% of that revenue, and
    they were using less than 2.5% of all the CPU's in the world! Oliver Mark
    at WarpStock 2003 in San Francisco last year commented that OS/2 in his
    European arena still accounted either directly or indirectly for over
    46 Billion of that revenue stream!

    More important, the biggest gripe the 'average' customer had with IBM was
    that it was taking over $250,000 a year per customer to still do the
    needed hardware and support work for OS/2. That despite the really good
    job IBM was and is still doing, as I see it!

    So your trip won't be necessarily easy. But your DOS platform could not
    be better bridged between the past and the future, in my humble view.
    I am VERY happy with IBM and what they have given me relative to DOS!

    Digital Research DOS: DrDOs does that.
    A Google search will get you there.
