Texas Instruments introduced with the Talking Master Mouse Computer the first kids' computer with a real working mouse.

This Mouse Computer sold in Germany looks very similar but uses a German voice. Please notice the unusual position of the "Z"-key. In France it was sold as L'Ordinateur Magique.

The screen of the Mouse Computer holds one of 10 activity cards. The 24 different activity choices offer a wide range of challenge levels and include engaging topics such as

• Next Letter
• Hidden Word
• Counting
• Guess My Number

and more.

The toy is intended for players ages 4 and up.

The Mouse Computer is a perfect combination of TI's superb speech synthesizer technology known from products like the Super Speak & Spell and the appearance of a small notebook.

Dismantling this Mouse Computer manufactured in June 1993 by Texas Instruments in the United States for the German speaking market reveals a rather complex printed circuit board (PCB). The design of the Computer Fun is centered around two different Integrated Circuits:

• TSP50C11/CSM11128A: TSP50C50 VSP (Voice Synthesis Processor) with 8-bit microcontroller and 16k Bytes Mask ROM for both program and voice and 128 Bytes + 16 Nibbles RAM
• Hitachi HD44780: LCD Controller for monochrome dot matrix liquid crystal display with 8-bit Interface
