ASSEMBLY PROGRAMMING
Assembly language programming capability is built into the TI-84 Plus.Asembly programs that have been previously made for the TI-83 Plus should be compatible and work with the TI-84 series of calculators. However any assembly programs made for the TI-83 will NOT work without modification of the code.
For software development, we recommend Brass, included with the Doors CS SDK, or SPASM.
