In 1998 the big Christmas toy was an interactive animatronic pet. How intelligent was it really? What hardware was crammed into the fluffy exterior? I guess there is only one way to find out - tear it down! http://bit.ly/2Xls86m The ICs are: An LM234 Adjustable current source (a power controller) an HT93LC46 - 1K EEPROM (non-volatile memory, or its storage) an IC with smudged text - although I understand it is an audio amplifier! and 2 potted ASICs which I understand is the CPU and ROM.
