Texas Instruments introduced with the Computer Fun a perfect combination of their superb speech synthesizer technology known from products like the Super Speak & Spell and the appearance of a small notebook.
The small graphics screen, the arrow keys and the function keys let you play one of 12 different preprogrammed games.
• Letter Play: Letter recognition and keyboard layout
• Number Play: Number recognition and counting skills.
• Creature Creation: Creativity and imagination.
The toy is intended for players ages 4 to 8.
Dismantling this Computer Fun manufactured in July 1990 by Texas Instruments in the United
States reveals a rather complex printed circuit board
(PCB). The design of the Computer Fun is centered around four different Integrated
• TSP50C44/CSM44012: 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
• TSP60C19/CMM19006: VSM (Voice Synthesis Memory) with 256k Bits
• Hitachi HD44102: Column Driver for monochrome dot matrix liquid crystal display with 4-bit and 8-bit Interface for up to 50 columns
• Hitachi HD44105: Common (Row) Driver for monochrome dot matrix liquid crystal display with 4-bit and 8-bit Interface for up to 32 rows
The regional definition of the Computer Fun is accomplished with different Mask Versions for the ROMs of both the VSP and VSM:
• American Voice: TSP50C44/CSM44012 and TSP60C19/CMM19006
• British Voice: TSP50C44/CSM44017 and TSP60C19/CMM19040
• German Voice: TSP50C44/CSM44024 and TSP60C19/CMM19xxx
In other countries like United Kingdom the Computer Fun got not only other voices, even the keyboard layout changed. Don't miss the German Computer Fun.
Later a similar product was sold with the Mouse Computer.
