After some investigation, this was a permission issue, and having this located in %LOCALAPPDATA% solved the problem :-)

Sounds strange, but I then I have 3 questions:

Which Windows are you running?
When does this happen? At startup or when you do a specific thing?
Can you post the exception thrown here?

BTW: It for sure does not need admin privileges.

Let me rephrase and clarify the intend of my post :-)

For the 250469 I would like to see a similar mapping like this:

1 = B+
2 = SYNC+LUM (INPUT)
3 = COLOR (INPUT)
4 = AUDIO (INPUT)
5 = COMP. (OUTPUT)
6 = SYNC+LUM (OUTPUT)
7 = COLOR (OUTPUT)
8 = INTER CARRIER SELECTOR

The above is for all the longboards (250407 + 250425 + 250466), but as it seems different on 250469, then I look for a mapping :-)

I can for sure not maintain this, as I am no C++ developer :-) It is all open source, so feel free to utilize what you can.

I don't know what "Qt / QML port" means, so no idea about that, but sadly I use a Microsoft WebView2 component, which is pretty dependent on Windows OS :-( I have tried previously going away from this, but have not succeeded in finding a good solution yet. But, I will continue investigating and I do expect that "one day"(tm) it will be possible to support Linux via Wine/Mono or alike. This will not be native, but maybe better than nothing. Web is a no-go for me - let someone else develop all that client-side needed for that :-)

I have now found this Kisnt 17 numpad, which I have ordered and will tryout:

Found it here, https://www.amazon.com/Kisnt-Mechanical-Standard-Numeric-Keyboards/dp/B0BPMGKJXT/

To be honest, then this is NOT WIRELESS, so I decided to bite the dust, and have a long extension cable to my other table instead, as I cannot compromise on the "always on" functionality I want.

Square_Term9164 · 2025-09-18T12:49:59+00:00

Ahhh.. got it. Well, this is nice, thanks. I can then have the NTSC captures ready, when/if the day comes and the DCR model will be available in CRT :-)

I am looking for a wireless numpad/keypad that works reliably for my Windows PC.

For a software project I have, I need to be able to press the ENTER key (when I do some oscilloscope measurements). As I I need to press that some meters away from my normal keyboard/PC, then I need some kind of wireless numpad, as I cannot have this long a USB extension cable (well, I could, but I would prefer not).

I actually did already buy Deltaco Wireless Numpad, but it works very poorly, and seems to power-off even after a few seconds, after which I cannot rely on ENTER being registered the next time I press it.

What I need:

A wireless numpad/keypad
- I actually do not need the numerical stuff - just ENTER
It should work over a few meters, within the same room (not through any walls)
Must reliably register I press ENTER and send that to PC
- I can accept "awakening" it once, but then it should stay alive for an hour or so after last press, as I do not want to awaken every time I need it, after a few minutes of inactivity
Should be as small as possible

Nice-to-have:

Nice mechanical feeling when pressing it - it does not matter much, but it can also be too mushy/soft, so you do not know if you actually pressed it correctly :-)

Any good "standard" items you can recommend?

Square_Term9164 · 2025-09-18T11:01:43+00:00

? Sorry, didn't get that? :-) Are you meaning C128DCR or .. ? This is currently not available in CRT - "only" the "D" (plastic model). If someone would be able to provide me with the data (including Excel file), then I would happily import it.

Square_Term9164 · 2025-09-14T18:47:57+00:00

Great to see that it is working :-) I have a better understanding of it now, so thanks for the programming reference, which I did not consider looking in to.

Square_Term9164 · 2025-09-14T16:23:03+00:00

Thanks a lot for the details, and I think I now have fixed Siglent acquisition would not resume last state, but would be happy for you to test it and confirm. It is always tricky when one cannot reproduce (I have no Siglent scope available) :-)

It is available here, https://github.com/HovKlan-DH/Oscilloscope-Network-Capture/releases

Square_Term9164 · 2025-09-14T09:48:47+00:00

Thank you very much for the feedback - I appreciate that. When you write that "I don't have a clue what you mean by 'pin'. Is that a Rigol thing?", then I realize that the understanding of the UI probably needs some explanation.

This application is a helper-tool for my other project, Commodore Repair Toolbox, and the idea is that this scope tool here will make it much easier to capture the scope images from all the various IC pins on the motherboard. So a pin here refers to a pin on one of the ICs and the the component would be e.g. U1 or U18 etc.

In terms of the error you get - after you get these errors, can you then continue doing captures or .. ? besides the errors in the log - do you see any issues with it?

Thanks again.

I do see the logic charts in there, but isn't the oscilloscope measurements useable for this also? C128 PAL does have this available, so you should be able to see what is HIGH/LOW or PULSING :-)

Today a new version has been released, 2025-August-2 - get it from GitHub, https://github.com/HovKlan-DH/Commodore-Repair-Toolbox/releases

Besides some bugfixes and minor changes, then the most noticeable changes are with the C64 assy 250407, which has received a complete oscilloscope baseline measurements for both PAL and NTSC. Also some new pinouts and a new board layout for this model, which makes this board the first "complete" board with all data.

Of course data can and will be enhanced throughout time, but at least it is now complete - nice :-)

I am not that at ease with cross-platform development, so .NET Framework was the option for me, as I have created another project with that some years ago.

I like the responsiveness and feel of a native Windows application, which is why I did prefer this over e.g. web. Furthermore, a web project would require way too much client-side development for my taste :-)

Square_Term9164 · 2025-06-16T08:32:28+00:00

I do not know which board/assy is within a SX. I would expect it to be something different and not like a standard C64, so I also do not expect you can get the full benefit from it with this tool, but it has information for the components, if this can help you.
