The inside view of the later Speak & Spell (English voices) sports
a smaller printed circuit board (PCB) than previous models.

The PCB of a Speak & Spell (English voices) manufactured in April 1991 is centered around a TMC0271 Microcontroller,
a TMC0281 Voice Synthesis Processor (VSP), a TMC0350/CD62175 Voice Synthesis Memory (VSM),
and a small power supply and 9 character VF-Display. Please notice the extra space for a second VSM.
