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:

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: stardot.org.uk/forums/viewtopi…

A frequent post topic on STH , and indeed all similar retro forums, is where someone has a hardware fault and is asking for advice on how to go about fixing
