[9.18] Use Multiple Commands On Entry Line With - Texas Instruments TI-89 Tip List

Send the modified ROM to the calculator with TIBReceiver (You can find it on www.ticalc.org, read
carefully its doc!) Note that you cannot use the last version of TI GraphLink to send a modified ROM,
you must use another program, for example, I have used TilP.
Turn the calculator off, then on. Now the keys should be faster
All done! Simple! To be sure you have done the correct changes, before sending the ROM to the
calculator, use VTI to verify the modified ROM, try also to turn off and on the emulated calculator.
Technical explanation
(If you want to know more read this paragraph)
A TSR program that speeds up the keyboard installs itself as a replacement of the trap #4: in this way
every time the calculator is turned off and on, the new trap replaces the default values set by the AMS.
I have searched in all the ROMs the addresses of these instructions: move.w #$150,something and
move.w #$24,something. Then I have modified the values $150 and $24 with the ones set by the
program Fast Keyboard.

Disclaimer
Although this method has been tested, it is still remotely possible that it may do crash or hang your
calculator. I am not responsible for any damage done to your calculator.
