else than the UK version of the original Spelling B.
From a technical point of view the toy makes use of the technology introduced in 1978 with the Speak & Spell: The TMC0272 microcontroller is derived from the TMS1000 series and adopted to control both the keyboard and the display. A second microcontroller with the TMC1984 designation is used as an "external" memory. The TMC1980 series was used in other educational toys, e.g. the Math Marvel and DataMan.
In Germany the Spelling B got another language ROM and a slightly different design. Explore the Spelling ABC.
Neil Wiliams discovered recently a Spelling ABC (UK), it makes use of the printed circuit board (PCB) from the 2nd generation Spelling B
