    It's been a while since a I accessed Reg Edwards wonderful programs.
    In fact it was one computer ago!
    I now run Win 7 X64, And they don't run on this system."

    Any Ideas how I can make use of Reg's programs?

    Try a virtual machine. Sun's is pretty good and allows you to operate
    with legacy OS'es.

    If all else fails return to the last-known-good Windows OS which is XP.

    I looked at VMWare and VMLite, and went with VMLite.

    Les Cargill Guest Will expose a Vitual XP machine for you.

    No. I do not believe they can buy new licenses.
  6. Yes but it's a hampered, dumbed-down, version of Virtual PC,which MS owns
    only because they bought the company that developed it. Sun's VirtualBox is
    much better than the full version of Virtual PC,and is also free. If you
    ever need to work on a QNX system in a factory environment for example, you
    can become familiar with it on your own PC.

    64-bit XP or 64-bit Win7 has an advantage here, because you can have more
    than 4GB of RAM, and allocate a few GB to each virtual machine running

    Win 7 actually ain't too bad, overall. A little more glitz but basically
    it all behaves pretty much like XP.

    Win 7 Professional and Ultimate also both have a built-in* Windows
    Virtual XP mode. It's even possible to run an app that was installed in
    the virtual XP machine on the regular Win 7 desktop and start menu, as
    long as the app was installed for all users.

    It's not a 100% complete solution for every legacy app. MathCAD 2001i,
    for example, won't install because of the way Mathsoft (late, lamented)
    implemented their CD-based anti-piracy.

    Better if hardware virtualization is supported by the processor, but MS
    has a patch to allow non-hardware virtualization.

    * If not pre-installed, it can be downloaded from MS.

    4 GiB of RAM was the limit before Pentium II, but after that, the
    internal addressing capability was 36 bits, with potentially 64 GiB of
    physical memory addressability. However, some of the earlier
    processors did not bring out all of the extra high order address
    lines, limiting the available physical memory somewhere between 4 and
    64 GiB.

    IMHO, the only reason for using processors with 64 bit virtual address
    space is large data bases. It is very convenient to map a disk based
    multiple terabyte databases (spanning several physical disk drives)
    into a single virtual address space and access the bytes on disk by
    simply making memory references. The OS page faulting mechanism will
    load the referenced pages into memory and also write back to disk, if
    RAM is needed for more urgent needs (or by explicit flush requests).

    Thus in practice, a few gigabytes of actual RAM will serve as an L3 or
    L4 cache, while the real "memory" is spread over several disk

    Of course 64 bit virtual address spaces are not a new thing, I have
    used it on DEC Alpha since mid 1990's and I guess there have been
    earlier implementations.

    The Pro-version has a pretty good XP. You can run unsupported virtual
    machines on the others. 16bit code will not run native which broke some
    major product software installers. And you should probably bite the
    bullet and get Win7 soon you are *really* not going to like Win8.

    I reckon the new GUI looks like a cubist's bad acid trip. YMMV

    It might make sense on a tablet, but on a screen and mouse I reckon the
    user will end up throwing the mouse at the screen in sheer frustration.

    I reckon all even numbered versions of 'Doze are usually defective.
    Win7 has now been around long enough to have shaken down and be stable.

  12. Yes it does. I've been using it for old 32-bit legacy stuff. And so far
    it's been good. It's not perferct, but allows drive access and network
    As well as direct hardware hooks for serial ports LPT ports and USB
    ports. You have to download it separately, it's called XPmode.
    DOSBOX also works well for older DOS programs.

  13. There are still some floating around. Other wise you can go thru hoops
    and get the license and Images for XP embedded.
    which is XP but tailored for the hardware that it runs on. The SDK to
    create the image is about $3K, or you can get a freelancer to create a
    image for a few hundred dollars. XP embedded is essentially XP with
    certain components turned ON or OFF. This is purely OEM stuff but it
    may be possible to get an image for a system or two. The actually
    License is only $70 from a MS partner aka Arrow Elect or others. but you
    will still need to find drivers for the new hardware for XP.

  14. You mean running several VM's with a few GB each is not a valid reason?

    Maybe it wouldn't be if there was any hardware or OS support for 36-bit
  15. Guest

    In most cases, why would anyone put that amount of code and data into
    a single virtual address space ? After all, there are quite efficient
    means of communication between address spaces.

    The real issue with 32 bit WinXXX is that the virtual address pace is
    "polluted" by system DLLs loaded at default virtual addresses,
    effectively fragmenting the available address space. Trying to get
    more than a few hundred MiB of _continuous_ address space for shared
    memory sections or memory mapped files can be a challenge, long
    before the 2-3-3.5 GiB user mode virtual address space is exhausted.

    No, really - the VM solutions for Win7 work just fine. You can't
    load PCI device drivers, but them's breaks. You can load
    USB device drivers.
    cp -r -f <source> <dest> works great.

    Am I to understand that Win 7, which is what was being discussed,
    understands Unix commands?
  19. Les Cargill

    Les Cargill Guest

    I posted a link to a package. You have to install that first.

    Actually, it kinda sorta does. Launch "All Programs | Accessories |
    System Tools | Windows PowerShell | Windows PowerShell" and you'll get a
    CLI window that understands classic shell commands in Microsoft's own
    very special way.

    I'm sticking with MinGW and MSys on the Windows side.
