We encountered an error while trying to save the changes. We've made a note of it, and we'll fix the problem as soon as possible.
Next, we can remove the Bluetooth board from the iMac.
With the help of our trusty iFixit vise (which is made of the same material as our spudgers, and is ESD-safe), we're able to desolder the shield covering the little Bluetooth board to reveal the chip goodies underneath.
At its heart lies:
Broadcom BCM2046 Bluetooth IC
256 KB of SST 39VF200A CMOS Multi-Purpose Flash (MPF)
We found this same chip a long time ago in the first MacBook Air.
