Improvement of NTVDMx64

[Ioann705]

Hi, Mr Leecher1337.
I am using the latest version of NTVDMx64 to work with the old OrCAD software package. Conveniently, directly from WINDOWS. But I came across that some utilities still don't work. Memory protection error. I am enclosing this one. If you haven't abandoned the project, you may find time to improve the NTVDMx64.
Thank's and best regards.
PS: This is an exe-file, rename to exe and run under NTVDMx64. (On Window XP it's run is Okay).
ncdrill v.2.20.exe.txt

Missing dependency:
Stub ldr err 7: DOS-Extender file "dosxtend.exe" not found

Re: [leecher1337/ntvdmx64] Improvement of NTVDMx64 (Discussion #300) Hi, leecher1337. In my OrCAD's folder exists two extender's files, thear it's. And the sample of the board file: I will be very happy if you can help.

I can't find a board file in your attachments
How to cause it to fault?

Hi. I see that You can run this program without errors. Is this a new NTVDMx64 build? The my fault looks like this: (attachment) So, board file. And batch file with using switches.   Thank’s and best regards, mailto: ***@***.***

I attach the fault's screenshot, board and batch files here.

B-130CI.BD1.txt
drill.bat.txt

[leecher1337]

To execute, I'd also need the correspondig .drl file and also a .tc file, is it is asking for it:

C:\Temp\ncdrill>ncdrill B-120CI.BD1 /W /FLIP y ..\drill\B-120CI.drl /b c s
Ncdrill Version v2.20
        Copyright 1993-1994 OrCAD Inc. All Rights Reserved

ERROR (Ncdrill), Unable to open 'C:\Temp\DRILL\B-120CI.TC'
No such file or directory

Not sure why your copy crashes, I'm executing this nicely in NTVDMx64 on Windows 7.

Do you use CCPU or HAXM build? I'm using CCPU build

Re: [leecher1337/ntvdmx64] Improvement of NTVDMx64 (Discussion #300) I build the latest version of the ntvdmx64, and the ncdrill program is take an error. Only ncdrill program, other program of OrCAD 386+ are runing succefull. May be my build is differs from yours... How we can verify the binaries? I'm want to test it under win11 today, and will provide the results to you. You can contact me directly by my e-mail: yolkinivan__inbox__ru. This e-mail I look every day. Thank's and best regard.

[leecher1337]

What were your Win11 results?

[Ioann705]

Hello! I am very glad that you are not abandoning your project. This is a very good idea! Two programs: Your virtual machine and a GDI driver from someone ... whom I could not contact ... They allowed me to put the old OrCAD software package for developing printed circuit boards on a par with modern (and quite redundant for many cases, and very expensive software packages). I did not test this on Windows 11, because I use Windows 7 - I am a very conservative person by nature. Although I tested it with my son on a Windows 10 (or 11) computer, everything worked exactly the same. But I should note that the problem that I contacted you with (the ncdrill program) has reappeared. That is, the program does not work. Returns a memory protection error. My son has the same thing on his Windows 10 (or 11) computer. But it also has some kind of assembly, not an original one. Personally, I had to use the assembly from g0d1ke at work as a working one. I'm not using the original windows build, because it (the original one) has problems with usb3 and I can't use the built-in graphics in the Ryzen 5 core - I had to install a discrete graphics card. To generate the overlay file (Excellon), I now have to use WMware. Otherwise, considering that another equally good person made the GDI drivers for this software package, everything works just FINE!!! I wish you success in all your activities! I wish you good health and creative success!
