Comments

Hardware version 0 is the original TI-83 Plus, version 1 is the TI-83 Plus Silver Edition, version 2 is the TI-84 Plus, and version 3 is the TI-84 Plus Silver Edition.

On later versions of the TI-73/Explorer and TI-83 Plus (hardware version 0), this BCALL returns information about the LCD controller in B. The return value is checked bitwise, but appears to use the same higher power supply level regardless of which bit is set.
