The TI-1850 Visor Kit was introduced to track the performance of the car. The kit includes 5 pieces to clip securely to the car's visor:

• A calculator based on the TI-1001
• A clip-on tire gauge measures 0 to 50 p.s.i.
• A mechanical pencil
• A Auto Record pad to log date, dollar amount, mileage...
• A black wallet

About one year later an enhanced calculator for cars was introduced with the TI-2001 GTI.

Nevertheless continued Texas Instruments to manufacture the TI-1850 and changed the overall design. Don't miss the restyled TI-1850.

Find here an excerpt from the Texas Instruments Incorporated leaflet CL-199J dated 1981:
