Re: Product code.
If your TI-89 is a HW1 calculator, as opposed to HW2 (Hardware Version
2.00), then you don't really get any more memory. AMS 2.0x will give the
TI-89 a total of 702k Flash ROM. On HW1 calcs, you can only use 384k of it
for user data archive, and the rest can ONLY be used for Flash ROM apps.
However on a HW2 calculator, the full 702k can be used for user data archive
or Flash ROM apps.
To find out what hw version your TI-89 is, go to the about screen where it
shows your AMS version, and if it doesn't say "Hardware Version 2.00" then
its a HW1 calc.
