OSS tiny-c was a small C compiler disk.

From Atari FAQ:
First sold C compiler by OSS. This compiler was used to compile itself! First true language "bootstrap" on any 8-bit machine (it was also available for Apple and CP/M machines). Derived from Dr. Dobbs "Small C". Compiles to 6502 code which emulates the 8080 instruction set.
