Nothing
else than the UK version of the 2nd generation Spelling B.
The
printed circuit board (PCB) and electronic of this Spelling ABC (UK) is
identical with the US Spelling B manufactured mid of 1980. We noticed an earlier
Spelling B (UK) manufactured in March 1980 using
a different architecture.
In Germany the Spelling B got another language ROM
and a slightly different design. Explore the Spelling
ABC.
