More characters. Like the 85 and the 92.

I think 188k to play with, the Flash rom is for long term archiving.

No. The 92+ is simply a 92 with a plus module preinstalled. An 89 has
no plus module port.

No. But an emulator may emerge (like on the 86) for 83 programs on the
92/89, but as of now no. The 89 will run 92 programs, and vis-vesa.

No.

Somebody will have to take the time to write them. There are none now,
and I don't know if there will ever be.

Should work just fine. Look on TI's site for the free graphlink program
download. You may be able to use a the 92 version if the 89 version
hasn't been released yet.

Price. Also the 92 is not allowed on the SAT/ACT. The 89 might. The
92 is also bulky, won't fit into your pocket like the 83.

I might be looking for a 2nd hand 83 for stats soon. It depends on how
the 86 with adv. stats works out. If it has no scratches on the screen,
and the manual inlc. I may be interested.
BTW, anybody know if the 85, 86, or 86 w/adv. stats program can do a
normal probability plot?
