This close relative of the TI-1270 was sold as Citation from the distributing company Western Auto. Don't be confused with the Citation based on the TI-1000 calculator, this one is named 66-4988-3 which could be interpreted as M4988.

The only differences to the TI-1270 are the colour of the keyplate and the missing TI logo.
