Summary: Texas Instruments’ popular line of TI-83 and TI-84 calculators includes eight models, of which four are listed on TI’s Web site. What do you get by choosing one model over another?

The TI-84 Plus CE Python is listed on TI’s Web site, announced for “Fall 2021”. I don’t have anything to say about it on this page.
The TI-84 Plus C Silver Edition (TI84+CSE for short) was released in 2013. It adds color and higher screen resolution to the TI-84 Plus. Part of that screen resolution goes for a two-line bar at the top: the first row shows selected mode settings and battery charge; the second row sometimes shows context-sensitive help. All the math and statistical functions and graphs carry forward from the black&white TI-84 Plus, and there are some enhancements.
The TI-84 Plus C Silver Edition is no longer available from Texas Instruments, though googling for it (as of November 2021) quickly turns up retailers that still have it for sale. Though the TI-84 Plus CE (next paragraph) is a better buy, I’m keeping the TI-84 Plus C Silver Edition on this page. Those things are built like tanks, and you may be able to get one used and save some money.
The TI-84 Plus CE (TI84+CE for short), introduced in 2015, is about half the thickness of all the earlier TI-83s and TI-84s, a bit more rectangular, and 30% lighter (201 g versus 287 g). It has almost exactly the same menus as the TI84+CSE, but a new processor and memory-mapped LCD make it much faster — up to 300% faster, according to the review at Cemetech.net. It’s got more than six times the RAM of the TI84+CSE, which means greater capacity for programs and data.
I can’t see any reason to buy a new TI-84 Plus C Silver Edition. Despite lacking the “Silver” moniker, the TI-84 Plus CE is faster and cheaper than the TI84+CSE, and it has much more capacity too.

Since I last updated this page, Texas Instrments has released the TI-84 Plus CE Reference Guide. It’s less than half the size of the older Guidebooks, which can be a good thing or a bad thing depending on how you use manuals, if you use them at all.
Although the TI84+CSE is no longer sold by Texas Instruments, the Guidebook is still available, and it’s more than double the size of the Guidebook for the TI-84 Plus CE. Since the two models have nearly identical functions, you may want to download the larger guidebook to get more information.

GridOn and GridOff ; the color models give

The black&white TI-84 Plus and TI-84 Plus Silver Edition were released in 2004; there was no “original TI-84”.
TI upgraded the firmware on shipped models in 2010 and again in 2011, without changing the model names. If yours was manufactured before 2012, you can check the firmware version and download new firmware if necessary.
When I checked in November 2021, the black&white black&white TI-84 Plus was still being sold, but TI no longer has a page for the black&white TI-84 Plus C Silver Edition.
Besides color, what does a TI-84 Plus get you over a TI-83 Plus?
Both the TI-84 Plus CE and the TI-84 Plus C Silver now come with these features:
MODE
], as far as I know.You can control these features (except as indicated) by
pressing [MODE
] [▲
].
The keyboards are identical in labeling, but the 84’s design is curved, and all keys except the numeric keypad are smaller.
Added in 2.55MP: On the home screen, you can just press
[▲
] repeatedly to recall past calculations. When
you find the one you want, press [ENTER
]. It’s pasted to
the screen where you can edit it if you wish before pressing
[ENTER
] again to execute it. ([2nd
ENTER
makes ENTRY
] still
works.
The 84 has a clock, which you can view or set by pressing
[MODE
].
Added in 2.55MP: Four new “shortcut menus” claim to offer
faster access to existing functions; press [ALPHA
F1
makes FRAC
],
[ALPHA
F2
makes FUNC
], [ALPHA
F3
makes MTRX
], [ALPHA
F4
makes YVAR
].
Of these, [ALPHA
F3
makes MTRX
] really does seem to make it easier to enter
matrices.
There are a few goodies for statistics students:
STAT
] CALC
menu,
the [2nd
VARS
makes DISTR
] menu, and possibly others I haven’t
noticed. You can turn the wizards on or off by pressing
[MODE
] [▲
] [▲
].The [STAT
] CALC
menu has a new
item, D:Manual-Fit
.
The [STAT
] TESTS
menu has two new
entries, D:χ²GOF-Test
and G:LinRegTInt
.
The 83 screen is shown at left and the 84 screen at right:
However, χ²GOF-Test
makes you compute the
expected values on your own, so it’s not as useful as it could
be. (See MATH200A Program part 6 for a downloadable
program that does the whole job.)
The [2nd
VARS
makes DISTR
] menu has a new
entry, 4:InvT
, for finding inverse Student’s t.
The 83’s selections 4–E become 5–F on the 84.
The following catalog functions are in the 84 but not the 83:
χ²GOF-Test

The included Catalog Help application doesn’t describe these. Consult the pared-down TI84+CE Reference Guide.
Functionally these are almost identical. I know of only these differences between the plain TI-84 Plus and the Silver Edition:
The black&white TI-84 models go back to 2004, but some firmware upgrades added features:
If you program your TI-84 in C or in z80 Assembler, or if you use third-party programs written in those languages, you may want to think twice before upgrading the OS. Cemetech announced in May 2020 that OS release 5.5.1 for the French TI-83 Premium CE inhibits C and assembler programs from running, and also prevents you from reverting to an older OS version. A few days later, Cemetech reported that the same changes would apply in release 5.6 for the TI-84 Plus CE.
If you have a black&white TI-84, press
[2nd
+
makes MEM
] [1
] to check the firmware version. If
it’s older than 2.55MP, you can download new firmware
from
this page
to get
MathPrint and other features.
The original TI-83 was released in 1996, the TI-83 Plus in 1999, and the TI-83 Plus Silver Edition in 2001, according to Wikipedia.
Keyboard differences are few.
The TI-83 Plus replaced the original
TI-83’s dedicated
[MATRX
] key with an [APPS
] key, moving matrix
functions to
[2nd
x-1
makes MATRX
]. The finance functions from
[2nd
x-1
makes FINANCE
] on the original TI-83 were moved to a
FINANCE app. All the later TI-83/84 models have the same
keyboard as the TI-83 Plus, though the shapes of the keys have changed.
Programming differs a bit between the original TI-83 on the one hand, and all other TI-83/84s on the other. The TI-83 uses 83P program files; the others can run 83P files but natively use 8XP files, which the original TI-83 cannot run. 8XP files added new features, such as letting programs display lower-case letters.
The original TI-83 and TI-83 Silver are no longer listed on TI’s Web site, but the TI-83 Plus is. I don’t see any reason to buy a new TI-83 Plus, because the TI-84 Plus is about the same price and has more speed, more memory, and more features. However, a used TI-83 Plus can be a good buy; just spend a little time to make sure that the character and graph displays are working correctly.
Confusingly, there is a TI-83 Premium CE calculator, released in 2015 as the French version of the TI-84 Plus CE.
