TI-84 plus SE RAM

请教大家，TI-84 plus SE的RAM实际大小怎么看？
只能看到可用的24K显示。

RAM 128K版本，怎么检查到呢?
（拆机后看到的是TA3芯片，应该是128K）

Hi TI-84 Plus calculators can use 3 different ASIC chips :
- 83PLUSB/TA2
- 84PLUSB/TA3
- 84PLCR/TA1

TA2 and TA3 chips have 128K RAM.
The TA1 chip has 48K RAM.

You can check the hardware revision on the back of the calculator.
Look for the datestamp, at the right of the serial.

Let's take for example a P-0508M datestamp. It means the hardware revision is M.

Here are the rules :
- hardware revision G or below means a TA2/TA3 chip with 128K RAM
- hardware revision H or above means the TA1 chip with 48K RAM
