first glance this rare Speak & Spell
manufactured in Japan could be mixed-up with the Speak
& Math due to the grey housing.
Discovering this educational toy reveals a printed circuit board (PCB) and Speech-ROM's identical to the original US product but some interesting modifications:
|• The jack of the head phone
is placed above the display.
• The position of the jack for the power supply is slightly shifted.
An inside view of some other dismantled Speak & Spell products could be found here.
