Running PB DOS programs in WIndows 10 64 bit (and earlier 64 bit versions)

[Stuart McLachlan]

I came across this one while looking at the requirements for running 16 bit applications on 32bit Windows 10.

I haven't tried it, but it looks promising
http://www.columbia.edu/~em36/ntvdmx64.html

NTVDMx64 makes it possible to run old DOS applications under 64-bit Windows 7 and Windows 10. (It is reported to work correctly with Windows Server 2008 R2, and perhaps also with more recent Windows Server versions.)

NTVDMx64 does NOT make it possible to run 16-bit Windows applications under 64-bit Windows! It only works with DOS applications! To run 16-bit Windows applications, you may want to try otvdm/winevdm.

Unlike emulator applications such as vDos and DOSBox, NTVDMx64 is fully integrated with Windows, with the same access to the Windows file system and ports that NTVDM has under 32-bit Windows. NTVDMx64 does not perform as quickly as DOSBox or vDos, but its integration is a unique and important advantage. For example, a DOS application running under NTVDMx64 can print directly to LPT1 if the computer has a parallel port; this is impossible under DOSBox (although possible with vDos through a configuration option).

it is extremely interesting, thank you!

Yes...thank you Stuart

The MS-DOS Player for Win32-x64 allows the running of 16-bit MS-DOS .COM and .EXE programs on my Windows 10 64-bit system.

From the README.TXT

This emulator inherits the environment variables from the host Windows,
and a target command can access the host's file path directly.

So you can execute 16bit MS-DOS compatible commands on your 64bit Windows
in the same sense as you did on 32bit Windows, and you do not need to copy
any files to/from a virtual machine (VMware, Virtual PC, XP mode, or others).

NOTE: This emulator DOES NOT support Win16 execution files.

This emulator aims to support character user interface utilities, for example
file converters, compilers, assemblers, debuggers, and text editors.

NOTE: This emulator DOES NOT support graphic/sound hardwares and DOES NOT
aim to support game softwares. I recommend DOSBOx for this purpose.

Source code is also available.

So far, it runs my PB DOS programs with no problem.

Another alternative? http://www.vDosPlus.org

vDosPlus sees long and compressed 8.3 filenames, whereas the original vDOS ignores them.

Good link Israel. This developer is very verbose. I've used the portable Dosbox for older non-compiled small GW-Basic programs.
Have you used the windows or dos version of dosbox-x ?

[Israel Vega Alvarez 2]

I have only tried DOS applications and they work great.
Graphic libraries like IconToolBox for QuickBasic. It's fantastic. Compile and run fine. An old game ALLEY CAT and many more.

Greetings ...

Was not previously aware of DosBox-X. Now trying it out, and like it so far.

I see that it is a continuation of as well as a successor to DosBox. I am assuming that, with just a few minor variations, the configuration file for DosBox-x is a near-mirror of that for DosBox. If yes to that assumption, I assume then I can import a few essentials over from the old to the new. Of course, I'd keep a backup of the default Dosbox-X file handy just in case.

Wikipedia is definitely not yet aware of DosBox-X (at least as far as I can tell). Someone should get a page started on that.

Thanx-A-Lot.. Stay Safe and Well.
