[nfbcs] Running 16-bit DOS Applications Under windows-7 64-bit

[Mike Freeman]

Hi, Steve.

I believe I've seen the XP emulator also though haven't tried it. "DOSBOX"
is an actual package one installs which claims to run DOS applications -- I
believe it was crafted for game freaks who missed their DOS games under
Windows 7. I never thought of trying to install JAWS for DOS under it and
seeing if I could route to a DECtalk USB external synth but I doubt it in
that JAWS for DOS never knew anything about USB ports.

Oh well.

Mike

Mike,

I don't know if the Windows XP emulator is the same thing that you are
referring to or not, is DOSBOX part of Windows 7?  My understanding is that
a 
screen reader will run inside the emulator, but you have to install it just
as though you had it on a separate computer.  I don't know how the JFW 
authorization process looks at that although you might be able to get by
with NVDA.  However, I don't know how well NVDA works at a command prompt 
which is sounds as though you need.  I know of a guy who got NFBTRANS
running before we got it recompiled as a 32-bit application but I know he
had 
trouble communicating with printers and such from inside the XP emulator.
When you started it, did you try Narrator to see if it would come up?  That 
would let you install something else.  DOSBOX implies DOS only, though and
my understanding is that what I am thinking of actually ran a sort of
Windows 
XP VM.  It does sound as though you had some fun with the CPM stuff.
<smile>.

Best regards,

Steve
