Texas Instruments Spelling ABC
The
Spelling ABC educational toy is
preprogrammed to teach the spelling of simple words through different games
using a pictured booklet. In this booklet a lot of things are numbered and
Spelling ABC askes you to type the corresponding word. The German edition
contains 88 words each in three different categories adding to a total of 264
words. A nice feature of this game
is an added buzzer to give some noisy feedback.
This
Spelling ABC is identical with the 2nd generation US Spelling B
introduced one year earlier but uses a German language ROM and a different
keyboard plate.
From
a technical point of view the toy makes use of the technology introduced in 1978
with the Speak & Spell: The TMC0274 microcontroller is derived from the
TMS1000 series and adopted to control both the keyboard and the display, the
TMC0355 128kBit ROM stored in the Speak & Spell the Speech data.
