    Thank you for an excellent video. You really have shown me a lot ! The reset mod is ingenious, and the tool you found and shared is invaluable and will save me hours of tracing time. By the way, I once, just once, bought an untested board that actually worked ! But most end up in my fix-it pile.

      Thank You very much. Yes, sometimes You get lucky with untested machines and have just a simple fix, in most cases, it's properly dead :) I just published a new version of the reset circuit :) Cheers!

    Nice video. Question, taking the reset to low, basically is making a short? That is a doubt I have. Reset line is always at 5v, so linking it to gnd makes a short right and produce the reset. Is this safe?

    • @JosipRetroBits
      @JosipRetroBits  9 місяців тому

      Yes it is; that is how reset button works :) Reset line is not a power line, it's a signal line. It can be high or low. I do have a new version of this little circuit ua-cam.com/video/J8r-5bH86pA/v-deo.html
      Thank You for watching :) Cheers!

    Where was the broken trace at? I'm going through something similar rn and about to pull my hair out.. lol Nice Video BTW!

      I know how you feel :) At 3:16 (ua-cam.com/video/Y6tYIzj0WqE/v-deo.htmlsi=Jk4c6n2tGfB2JpiP&t=196) the first trace to the left of the pins. It was cracked but it was not visible with a naked eye. On this image is already fixed.
      If u can't see it (find it), use interactive bom to test all lines :) well depends on the issue.

      @@JosipRetroBitsOh, I'm sorry. I can see it in the video, I was just wondering where ON THE BOARD is it? Near logic? ROMs? VIC?
      thank you.
      Oh and interactive BOM is fantastic.. It's everything I wish C64 Parts locator was. Although, that's very nice too
