This one is still sitting on my “unfinished” shelf. If anyone out there is interested, I could easily be talked into finishing it. I wanted to make a Speak&Math with a large keyboard on it for controlling the pitch, so I had to build a new housing to accommodate the keys. I moved the circuit board from the S&M body and mounted it in
the new housing, but I left the original touch pad for accessing the regular functions of the S&M.
