	Games - Atari Assembler Editor

The Atari Assembler Editor cartridge was a program used to edit, compile and debug assembly language programs for the Atari 8-bit computers.

Details

The program was a two-pass 6502 assembler, in an 8kB cartridge. It was the first commercially available assembler for the Atari 8-bit computers.

Disadvantages of Atari Assembler Editor were speed, bugs, lack of macros and awkward conditional assembly features. Unfortunately, the program used the Atari's floating point routines for arithmetic calculations, greatly impacting performance. The debugger was really a monitor, limited in power and flexibility. Nonetheless, it was the only available assembler for the Atari for many programmers.

Aftermath

Although superseded by Atari Macro Assembler (AMAC), the Atari Assembler Editor continued to be used by programmers. Plus, Optimized Systems Software purchased the original rights from Shepardson Microsystems. OSS then came out with improved versions, one of which was EASMD.

Trivia

Programmer was Kathleen O'Brien of Shepardson Microsystems
, Inc.
