There are a lot of differences between American English and British English, therefore Texas Instruments had to change the Speech-ROM's of the original Speak & Spell to sell it on the United Kingdom market.
pictured Speak & Spell (British voices) was manufactured late in 1980 and
sports already the two additional jacks to connect an external power supply and
a headphone. The printed circuit board (PCB) itself is identical with the
original Speak & Spell but sports different Speech-ROMs. The CD2303 resp.
CD2304 designation indicates the Custom Data stored inside.
An inside view of some other dismantled Speak & Spell products could be found here.
The pictured Speak & Spell sports the button keys with the huge TI logo, we know four different designs:
|Version||Manufactured||Word List||Keyboard||TI Logo|
Even the Speak & Spells with the United Kingdom Speech-ROMs received all three designs, don't miss the early UK Type 2 and the later UK Type 3. Don't miss the rare Japanese edition of the Speak & Spell.
