Hi, I would like to collect all the Date codes of CX & CX CAS Calculators, I have found: P-0516AB so far. Could you guys post your date codes if you own such a calc?

I'm sure there is a list available somewhere like on datamath, or maybe ask critor, but mine has the datecode P-06140.

Oh boy.

It turns out that TI-Planet has been collecting datecodes/revisions for many years now (see here and here for instance, the latter pointing to a shared spreadsheets with lots of info), and we try to document each and every Nspire hardware revision, including the insides of the calcs (examining the motherboard, etc.) You can find lots of topics about motherboard and components comparisons etc. Here's one for example: https://tiplanet.org/forum/viewtopic.php?t=12898&p=147234 and a more recent one with a graphical comparison tool for the motherboards: https://tiplanet.org/forum/viewtopic.php?t=16904&p=185924

"Lately", I've also asked even more people from outside (on reddit, for instance), but also via MyCalcs, so that we can know what TI's been making over the years.

A (somewhat outdated) sample of the table I've been making is available on HackSpire (although I guess I should update TI-Planet's wiki page about hw revs...)
It looks like this now: https://i.imgur.com/mhbuoxl.png

Later, when I have the time, I'll have those datecodes and revisions properly organized in a DB with a page that can display them nicely (more specifically focused on that than the MyCalcs pages)


I think you can't even begin to imagine the many dozens of hours spent here and there regarding HW revision tracking and documenting (Also, notipa/CVSoft has been doing the same, perhaps even more extensively, for the TI-82)

Thanks, Do you know what the latest revision is?

Nspire hardware revisions have two letters now, the latest known one is >= AB.

AC? Wow that is quite new, is it the newest?

It's been about a year since I've done any real work on that (eBay is now deficient in early models but my bookshelf is not), but I was also comparing the gap between the numbers and some other small external changes.
