Nice one. Looks I'm also need to post some my photos from 2018, when I first found this buddy.
>Here's< I also posted quick background that related to that cancelled Nokia N-Gage device,
and also attached many my internal/external photos of it's HW in original size.
And btw, the official commercial name of the unit planned to be "N-Gage IC". So, you can update the thread name from:
'Planned successor to Nokia N-Gage QD found!' to the 'Nokia N-Gage IC. Cancelled Nokia N-Gage and N-Gage QD Official Successor.",
for the better indexation. But that's for sure for your choice.
