this is my assessment of the situation. my opinion could change...
@0x47df where is the option for black and white ti84+ /j
@ezio i haven't had any TI-84+ to make my assessment on, but i assume they are close enough to the CE anyways.
i have had TI-83+, and i did not get on so well with it. i kept it because i can at least run houstontracker on it. if it will not make me happy running numbers, it can make some chiptune. that's a reason to keep it.
@0x47df theyre slightly better, imho. iirc they added anti-assembly stuff to the newer firmwares on the 84CEs which is not cool, meaning you have to jailbreak them with exploits

the 84+ does not exhibit such issues, which is why i bought one a couple of years ago when my 83 died
@ezio mmm, I traded my CE for an 83 pocket Fr within a few days of getting the CE.
I still don’t vibe with the older TI calculators. Idk why.

@ezio @0x47df The 84CSE (basically a prototype version of the CE hardware in the bulky AF older case; AFAIK the main difference is that the CPU is somewhat slower?) has no such restrictions IIRC, but I haven't checked recently because I don't need to use that awful thing anymore. (It's excruciatingly slow even by TI-84 standards)

If I remember the drama of the time correctly, the assembly restrictions are probably because someone figured out a way to jailbreak the calculator to invalidate some of the "test mode" protections (disable programs for the duration of an exam) using an assembly program?
