"The Atari Assembler Editor is a cartridge-based development system used to edit, assemble, and debug 6502 programs for the Atari 8-bit computers. It was programmed by Kathleen O'Brien of Shepardson Microsystems. It was the first commercially available assembler for the Atari 8-bit computers.In the manual, Atari recommends the Assembler Editor as a tool for writing subroutines to speed up BASIC, primarily because assembly times are extremely slow for anything but the smallest programs."@en .
