Random Information
- Application note used is dated 1986
- The SPO256 chip recieves parallel data from the address lines in this implementation
- The text to speech algorithm used in the CTS256 chip was developed at Naval Research Labs in the 1970's
- The External EPROM is "erased" by UV light, ambient room light will cause problems after (alot of) years
- The application note has a different Parallel Panel schematic than the one supplied with the CTS256 chip
- Parallel Panel has Eight Data and Two Control pins mid board edge and break the aesthetic
- The 3.12 Mhz Crystal for the SPO256 is difficult to get, so this implementation uses a 3.2 Mhz Crystal
- JAC_101 has sworn not to do another project with the SPO256 chip, because he is out of them
