If TI would make color calcs, they should also add much more memory in their calcs!

They should do that anyway...

I think that even hardware-supported grayscale in black-and-white would still be a pretty good advancement. That way, the TI OS would actually use it, and it would look nicer. It wouldn't be as pretty as color, but it shouldn't be too much more expensive.

The nice thing about having muliple colors per pixel is that they can sort of make up for lack of resolution (for instance, you could use anti-aliasing). Of course, higher resolution displays are always nice, too.

Yes, this would be handy. The older iPods (non-color) have built in gray scale and look great. Being able to shade graphs with grays rather than ugly patterns would be very convenient.

Some simple hardware-supported grayscale would be nice - just have a divider controlled through one of the processor's ports, running off the system clock, that switches the memory mapping of the display...it would make programming easier, and wouldn't drain the batteries faster or add to the price significantly.

Remember that joke news thing about the Voyage 400 with the color screen?

It's screens are 9.375 MB files (240x160, 256 colors)

Actually, 240*160 only comes out to 37.5K...perhaps you used 256-byte color instead of 8-bit color (which is 256 colors). Remember to take log(numcolor)/log(256) to get the right number of bytes/pixel...although ~3*10^616 colors would be really cool (but not to useful for humans). :)

Color would be nice BUT I love my TI92+ for running looooong times without new batteries.

Those times will be over then :-(

In my opinion a better resolution and "real" grayscale in AMS would be better (to support at least such qualities as old on Palms)

Not necessarily...a reflective screen (like the GBA) would not draw any more power (except the extra circuitry...so maybe a factor of 8 on the display driver chip power consumption). Or, better yet, a transflective screen (so you could use it in sunlight or in the dark & have the optimum power consumption).

A color screen would be a definite improvement to TI's calculators. But realistically, I don't think TI will implement such a feature in the near future; they simply don't have any incentive.
What would be nice in the meantime is, as others have mentioned, built-in grey scale support (maybe 8-level). In my opinion, it should be hardware-based rather than relying on the operating system. That way, *I think* it would be possible for assembly games to rapidly shift the different levels of grey-scale, resulting in many more different shades. That would be a great improvement.

No incentive? It is much easier to descipher graphs of more than 2 or 3 functions if they have separate colors, it would help with shading above/below & still being able to see other functions, it would let my cellular automata program use more states per pixel, & the list continues...but I suppose most of the things with which color would help (except games, of course) are at best niche markets (well, maybe the multiple graph thing).

Does anybody know where to find a replacement lcd display for a TI-89?

a broken TI-89

They're nearly impossible to connect correctly without special tools. (Trust me, I've tried) :)

All of these survey questions are interesting...anybody know if a color calculator is actually being produced by TI or some other company?

Uh, I think one of the Casios has color (see a previous post)...

Several. Not just one.

Did you mean the same kind or to change to another display? I doubt there are any other compatible displays (at least, no color ones).

I dout that there are many 160X100 LCD's that read from memory that is 240X128. except those in 89's

Same here where do you get one for an 83+ without stripping another caculator
