The Z83 C Compiler is an optimizing cross compiler for a language very similar to C targeted toward the TI83+. The output from the compiler may be assembled with TASM (http://home.comcast.net/~tasm/) or ZASM (http://lpg.ticalc.org/prj_zasm/).
tisdcc is a C-compiler and library for TI calculators with a z80-processor (TI-73, TI-82, TI-83, TI-83 Plus, TI85 and TI-86). It allows high-level coding for these calculators without the slow speed of TI-BASIC and without the hassle of learning asm.
