What is the difference between Hardware Version 1.0 and 2.0?
TI frequently makes running changes to the hardware of its calculator products. If you purchased a
TI-89 after July 1999, it may include some minor hardware updates as described below. You can
identify these calculators by the statement "Hardware Version 2.0" on the About screen (press F1,
A:About...). All TI-92 Plus calculators have Hardware Version 2.0.
! Altered the management of the user portion of the Flash ROM. You will recognize this update only
when the Advanced Mathematics Software Version 2.0 operating system is installed. With
hardware version 2.0 and the 2.0 operating system, you have more user archive space while the
total amount of Flash ROM is unchanged.
! Once a user has loaded the 2.0 operating system and a few applications, the hardware version 2.0
and the original TI-89 are practically the same. This scenario is expected for most users in the
future as many great application ideas are floating around.
! Slightly increased the processor speed from about 10 MHz to about 12 MHz.
! TI-92 Plus only: Removed the TI-92 Plus Module compartment.
Note: New TI-89 operating system software, Advanced Mathematics Software v1.05, was required to
support the hardware changes. Therefore, Hardware Version 2.0 will reject earlier versions of the
operating system software.
Texas Instruments FAQ for the original TI-92
http://education.ti.com/product/tech/92/faqs/faqs.html
This FAQ applies to the original TI-92, not the current TI-92 Plus. However, much of the information is
still valid, and it answers more questions than the TI-92 Plus FAQ.
