TI Announces TI-84 Plus, SE; TI-89 Titanium
Posted by Michael on 7 January 2004, 22:25 GMT

TI-84 Plus Silver EditionTI has announced two new calculators for release in the spring: the TI-84 Plus and TI-84 Plus Silver Edition. Both are fully compatible with the TI-83 Plus and TI-83 Plus Silver Edition. Both have new physical styles, an integrated USB port for computer connectivity, an internal clock, and an available kickstand.

The TI-84 Plus features 480 KB of flash memory, 24 KB of user RAM, and a 15 MHz clock speed, while the TI-84 Plus Silver Edition has 1.5 MB of flash memory, available interchangeable faceplates, and is also 15 MHz. If you haven't already guessed, the Silver Edition, like its 83+ counterpart, is silver in color.


TI-89 TitaniumFor the summer of 2004, the high-end calculator line gets a metallic lift with the TI-89 Titanium. In addition to tripling the memory to 2.7 MB of flash, it also features a built-in USB port for computer connectivity as well as the kickstand slidecase (I'm not sure if this is included or an add-on, I think it's purchased separately). All three calculators feature high-contrast LCDs and are compatible with TI's projection devices (like ViewScreen).

Update: According to this press release, the 84+ will retail at $109.99 and the 84+ SE at $129.99. It seems that these are intended 83+/83+ SE replacements. The TI-89 Titanium press release quotes a street price of $149.99.

I'm gonna guess atleast $120 for the 84 series and $200 for the new 89. I'm getting the 84+SE no matter what though... tired of getting my 68k calcs banned from tests.

I doubt $200. That is a little much. Was the V200 $200? I thought it was $150.

The V200 was $200, ostensibly. It can be found for much less, though.

Well it's only $50 more that what a regular 89 sells for now. Then you add the cost of the new hardware (USB and memory) and the link cables that come with it it could reach $200 quite easily.

Well so much for that. I was right in between with the 84s with a guess of $120 - $140, but the 89 at $150! Hmm.. that was kinda out of nowhere, but hey I'm not complaining. Lower price means more likely I might get one.

^^^^^^^^
Here is a very detailed side-by-side comparison of all the current calculators, including the new Ti-84, Ti-84 Silver Edition and Ti-89 Titanium. It is in .PDF format. The link is above this message, where it says "(website)".

Actually that is one every current basics calculator page that we have on this page. It's one of the things I put on the basics pages when I redid them all.

so your paying an extra $50 for a usb hookup and more memory? sounds like a waste to me...

Exactly. You can just use SilverLink, and if you want more memory, use a USB FLASH ROM stick.

The USB port should be faster.

How? Same baud, serial, not parallel, just the converter is inside the calc.

Not if the other hardware can't keep up with it.

<sarcasm>Don't forget the clock!!!</sarcasm>
Seriously though, wouldn't that mean the 84+/84+SE have to have NMIs?

I thought about that, but I don't think so. Having an NMI would interrupt all the LCD operations, and would crash programs that swap in other RAM pages or otherwise do things with the stack or use shadow registers. If they really maintained compatibility, then they'd use one of the really cheap RTC chips that the semiconductor division of TI sells and interface it through hardware ports for reading/setting the time.

I'm not sure whether you are right about NMIs messing everything up; there should be ways to get it to work. For instance, as long as the NMI routine doesn't touch the LCD driver, there shouldn't be any problems (to the best of my knowledge, there are only minimal wait times, not maximums).
Anyway, you're right, putting in a RTC is likely a better idea. It doesn't cost much, there are plenty ports free, and it saves the problems of a mayor design change.

I made a clock in Z80 BASIC a while ago with nested trig functions.

It sounds like this is gonna be a clock just like a computer has one; when you turn it off, leave it alone for a while, and then turn it back on, it'll still show the correct time.
Side note: you can't make an accurate clock in Basic, as the speed at which the CPU executes instructions (and therefore, the speed of your clock) depends on battery level, temperature and some other factors. In order to have an accurate clock (or clack ;) ), you need cristals, which currently only the 83+SE and Voyage200 have (and the 92???).

Don't forget the HW2 TI-89/92+! And I doubt the TI-83+SE has one, although the 84+ probably does.

The 83+SE does have crystals that could be used to keep a clock. However, they run on interrupts, which can be (and frequently are) disabled, freezing the clock. The most important situation where the timer interrupts are ignored is when the calc is off.

I know that. I did a science project on BASIC clocks and timing and the very next year one on variations in CPU execution speed.

'Extra $50"? According to TI, the TI-89Ti is going to retail at $150, while the normal TI-89 currently sells at TI's web site for $160. I think. They might've changed it, though.

The 92+ is absent from this document. Has it fallen to the same depths of the 80, 81, 85, and 92, never to be seen again, except in the hands of loyal programmers and gamers, wishing once agan for the days old?

Which reminds me, IT'S IMPOSSIBLE TO FIND BETA TESTERS FOR TI-92 PROGRAMS! UGH!

As far as I know, they stopped producing it as soon as they released the Voyage 200, so it is already discontinued.

PS: However, AMS upgrades are still released for the TI-92+ too, and I hope it will stay that way for the forseeable future.
