Here's how it goes: To get into the "info screen", press AMS 1.xx: F5, (Diamond), APPS AMS 2.xx: F5, (Diamond), CLEAR Next, you can do one of many things: [alpha]+R: Remote control mode (you must have something to send commands with!) [alpha]+S: Self-test. Use this to test certain things on your calculator. WARNING: This WILL reset your RAM, and maybe even your Flash ROM!!! I've heard that there is a way to see a list of the people that helped produce the TI-89's AMS, but I haven't found it yet... Also, while in Remote Mode, you can't control your own calculator!!! You must control it via the link port... If you can't get out, just remove a battery and put it back in. You shouldn't lose your RAM, unless you have a low backup battery.

On mine it was the diamond, then the apps key, not the clear key. And it gave the same, no credits, just copyright info.

The true nature of this egg is not shown here. If you do the above, then press alpha "S", then you get a list of various self-tests, some of which are entertaining. Some of them clear your memory, but you can get out of the menu without clearing your memory. One consequence: this removes that little line at the bottom of the screen, above where the "busy" and "2nd" and stuff appear, but below where your input text shows up.

From the copyright menu.. press Alpha then S. This also works for the other TI graphing calculators too but only when you press Mode first, not in the copyright screen.

"mkay"...in any graphing calculator that Texas Instruments makes, (since 1990) the self test has deleted RAM and nothing else. It has never been a link to credits, and has sure as hell never been a pre-cursor to them. Anyone who tells you otherwise gets hard on the fact that you might lose important files.

Hm, I can get to self-tests fine. F5, Diamond, Clear. Unfortunately, my TI-89 doesn't pass the FLASH check. The RAM check creates an entertaining repeating pattern of vertical lines, however I'm pretty sure it's broken because I have to hit ON to get out of it and that dumps me back to the main screen with my RAM all reset. Please email me at me__ at mac dot com if you can tell me how to get it working again. Unless it's supposed to do that for a LONG time. Please tell me either way - only people who have actually performed the test on their calcs please. I'll probably flash this thing anyway, the base code is garbaged, and I'm on the rebound from a BAD flash-related lockup.

has anyone gotten to a menu of hardware tests from inside this copyright screen? (if you haven't, please don't go poking blindly at keys; i have crashed my -89 several times trying to get the menu again after the first time i saw it) please feel free to email me if you know anything about this.

Cool, it works on my Ti89 also.. Also, I think I found a really cool easter egg in the Ti89 Calculator. When you enter 1.5.8 for example, after I press enter the answer was one point two. When I looked to the left in the home-screen, I noticed that it read 1.5*.8 the * was added. Even though I did not press the * key. when I entered 1.5.8.
