Atari Assembler Editor (original) (raw)
Atari Assembler Editor (sometimes written as Atari Assembler/Editor) is a ROM cartridge-based development system released by Atari, Inc. in 1981. It is used to edit, assemble, and debug 6502 programs for the Atari 8-bit family of home computers without the need for additional tools. It was programmed by Kathleen O'Brien of Shepardson Microsystems, the company which wrote Atari BASIC, and Assembler Editor shares many design concepts with that language. The source code to the original Assembler Editor was licensed to Optimized Systems Software who shipped EASMD based on it.
