Actually, the This Does Not Compute video linked on this page on the teardown shows the 64110 as well at 2:39.

Actually, watching the stereo mod video shows the 64110 module in both the video and the SPI programming utility, so I guess it should work? https://www.youtube.com/watch?v=3zQo1gON...

The bluetooth module change is a bit of an issue with some mod tutorials available on youtube - be wary about attempting to modify one of the newer speakers to support stereo pairing with a USB SPI, as the CSRA64110 doesn’t support that as hinted at above.
