Texas Nspire "Clickpad" CAS calculator: What's inside (hardware view)

[debrouxl]

Nice photos indeed.

The fact that there's no serial number or date code on the back (picture #2) is highly unusual, given that even most prototypes have serial numbers of a different variety.
The 73 VSC prototype I picked up from the previous libti*/gfm/tilp maintainer, who received it from TI, had no writing on the back (not even regulatory FCC notes), and a sticker indicating that it's an engineering sample not for sale, but that's pretty much the only other such calculator that I can remember of.

BTW: the correct case for "nSpire" is "Nspire"
