Here’s the schematic and hardware layout for the C1 edition Speak&Spell, Math and Read.
I still have a few finished units for sale. see the for sale page. If you have to have one and don’t feel like making it yourself, drop me a line at pete (at) casperelectronics (dot) com

Please read the notes for this schematic on the Speak&Spell bending page before attempting the modification illustrated above.
