The
Mr.Challenger educational toy is
preprogrammed to teach the spelling of simple words through different games. A
nice feature of this game is an added buzzer to give some noisy feedback.
The Mr. Challenger was one of three similar games:
 | Math Marvel: Basic mathematics |
| Mr. Challenger: Word games |
| Spelling B: Spelling games |
All used the same housing featuring a coloured key plate to
cover some unused keys of the matrix. The display was either numeric for the
Math Marvel or alphanumeric for the two word games.
From
a technical point of view the toy makes use of the technology introduced in 1978
with the Speak & Spell: The TMC0273 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.
Compare this game with the German LETTERlogic
and a LETTERlogic sold in United Kingdom.
Some parts of the toys housing could be found in an industrial product, view the Model 510 PLC programmer.
