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.

SpeaknSpell_UK_PCB.jpg (188730 Byte)SpeaknSpell_UK_1.jpg (69483 Byte)The pictured Speak & Spell (English 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-ROM's. 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 three different designs:

Version Manufactured Keyboard TI logo
Type 1 1978-1980 Button big
Type 2 1980-1985 Membrane big
Type 3 1986-1990 Membrane small

Even the Speak & Spells with the United Kingdom Speech-ROM's reveived 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.
