What’s Different between TI-83 and TI-84?

Summary: The TI-83 and TI-84 are nearly keystroke compatible, but the 84 has a few new functions that the 83 lacks. This page lists them.
See also: TI’s own Comparison chart shows all graphing models, not just the 83 and 84. But it’s fairly high level and doesn’t mention specific functions.
See also: The TI-84 Plus and TI-84 Plus Silver Edition Guidebook is hard to find at the TI site, but is mirrored here (3.8 MB PDF). It’s also on the CD that came with your TI-84.
This page compares the two models I have, the TI-83 Plus Silver Edition and the TI-84 Plus Silver Edition. I know of only these differences between the plain TI-84 Plus and the Silver Edition:
If you have a plain TI-84 Plus, I’d be grateful for a report of any of the functions listed below that your calculator doesn’t have.
The keyboards are identical in labeling, but the 84’s design is curved, and all keys except the numeric keypad are smaller.
The 84 has a clock, which you can view or set by pressing
[MODE].
There are four new goodies for statistics students:
On the [STAT] CALC menu, there’s a new
item D:Manual-Fit.
On the [STAT] TESTS menu, there are two new
entries: D:χ²GOF-Test and G:LinRegTInt.
The 83 screen is shown at left and the 84 screen at right:
On the [2nd VARS makes DISTR] menu, there’s a new
entry, 4:InvT; see
Critical t on the TI-83/84/89.
The 83’s selections 4–E become 5–F on the 84.
TC3's MATH200 students care only about
binompdf, which is [2nd VARS makes DISTR] [0] on the 83 and
[2nd VARS makes DISTR] [ALPHA MATH makes A] on the 84,
and
binomcdf, which is
[2nd VARS makes DISTR] [ALPHA MATH makes A] on the 83,
[2nd VARS makes DISTR] [ALPHA APPS makes B] on the 84.
(Of these new statistical features, only χ²GOF-Test
is relevant to TC3’s MATH200 class, and this Web site contains a
TI-83 program that does
more.)
The following catalog functions are in the 84 but not the 83:
χ²GOF-TestcheckTmrClockOff and ClockOndayOfWkExecLibgetDate, getDtFmt, getDtStr, getTime, getTmFmt, getTmStrinvTisClockOnLinRegTIntManual-FitOpenLibsetDate, setDtFmt, setTime, setTmFmtstartTmrtimeCnvThe included Catalog Help application doesn’t describe these.
Consult Appendix A of the Guidebook for
the use of these catalog entries — except for
ExecLib and OpenLib, which seem to be
undocumented.
