I hate to burst your bubble, but you missed the point completely. Consider
this.
MPE developed a CM (compatibility mode) when the operating system went from
16 bits to 32 bits. The CM environment allowed existing 16 bit programs to
run on this new 32 bit OS. In fact, many components of the OS remained in
CM for many years. I am not sure but I think there may still be some CM
components in MPE, though I would not put any money on it.
Windows 3.11 actually brought on some 32 bit components to Windows. Some
aspect of the file system moved quietly to 32 bits. When Windows 95 came
out, it was a mixture of 16 and 32 bits. The 16 bit applications ran in
their own virtual machine on Windows 95. The 32 bit applications that
started to come out, were able to take advantage of the 32 bit
architecture, with expanded limits, threading and protected mode.
Windows NT first appeared in the early 90s and even though it was a
completely new and completely 32 bit OS, it was able to support many 16 bit
applications, especially if they did not try to take control of the
machine. Sort of like CM applications that ran in PM and diddled OS
reserved areas on MPE.
If one takes the time to read the caption at the link you so thoughtfully
provided, one would see that Windows XP offers the possibility to start an
application, be it 16 or 32 bits in a virtual machine that will emulate an
earlier version of a Windows operating system. That is new. Compatibility
Mode is not new on Windows, but emulating one of a choice of earlier OS,
that is something the HP 3000 does not do.
What remains to be seen is how good this feature is and how faithfully XP
emulates an earlier OS for an application, all this without interfering
with other applications.
Kind regards,

Looks Like M$ thinks Compatibility Mode is a good
idea. Hummmm...How many years has the e-3000 had CM?
How many programs from 25+ years ago CAN run on
current 3000 hardwar? Good job Bill. What else can
we teach the folks at M$ -- MACEBOBO
