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

[Steve Jacobson]

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
