Yep, it’s been half an hour and no dropouts… I’m calling it, my lovely new BBC Micro B is fixed :) Yay! Soooo excited to play with it tomorrow 🥳 Here’s a before video: https://vimeo.com/1181523949#t=26 And an after: https://vimeo.com/1182284426 And the issue, for anyone else who stumbles on this thread, was the 16MHz oscillator circuit (marked X1 on the main board). Also, I could only find a lot of 50 of them, so if anyone needs one, just hit me up and I’ll send it to you :) Huge thanks to the folks on the stardot.org.uk for sharing the fix: https://stardot.org.uk/forums/viewtopic.php?p=246304#p246304 #BBCMicro #BBCMicroModelB #video #dropout #issue #fix #x1 #oscillator
