Nice to hear a local accent in a video like this! Cheers fae west end Glesga :) BTW, is that a loud AC hum behind your voice? I could give some tips to filter that out, depending on what software you're using to record and/or edit.
The only cap that ever need changing on those boards is the tantalum on the 12V rail - and it won't boot when it needs changing. The rest are over-spec and pre-date the electrolytic cap plague of the late 80's and 90's. Other than regular issues with the lm1889n modulator (same chip as on the rubber key spectrums) the only thing that goes wrong is the 4116 DRAM and then normally from mishandling the board or messing around with the power supply board
@@fixornofix I've reproduced the original Dragon 32 boards (not the issue 5 that you have) and have a reasonable idea of how they work now. For all that the overall design is a bit behind on video and audio compared to other 8-bits of the era, the hardware itself is surprisingly good, and reliable!

That is nuts!

Thanks for the info. Never even seen the Dragon before this one, was a Sinclair and BBC micro guy.
