Since you offered: what is that trace called that is presumably electrically connected to the ceramic cap solder seal? I've wondered about its function, but have never been able to distill the prior sentence to the necessary power words. Also, here is an extra ham-fisted attempt to get you to cover an off topic interest of mine: did you know that the Soundblaster DSP was an 8051? Cool, huh? pleasedoan8051deepdiveimbeggingyouplease. I'm aware of only one gate level analysis, with evidence of its existence on archive.org... tragically the spider never bothered with the actual zip file and the author is long gone. Thanks for all the great reads, btw.

  The gold trace connects the metal lid to pin 1 (ground). This provides some electrical shielding. As for the 8051, I might look at it at some point, but I've got lots of other projects...

    ha, and here I'd assumed there was some convoluted vacuum getter / ion pump at the root of it... nope, just didn't wanna screw about with the bond wires. Thanks.

Amazing blog, glad I found it and the other articles look great too! Very interesting history of computing. Can you use an arbitrary waveform generator to make these sounds accurate or differences nonexistent? Do you think that good audio can be “solved”? I’ve heard of Harmon tuning and people’s preference for it, and how good speakers are all tuned the same but high end headphones don’t. I remember this person who knew electronic design destroying the credibility of head-fi. https://nwavguy.blogspot.com/ https://nwavguy.blogspot.com/ what do you think of forums like audio science and his findings?

  Well, you could feed the right digital values into the arbitrary waveform generator, but you have the problem of how to generate the values. As for your other questions, I don't really know anything about audio.
