Byte Works Inc.

The Byte Works, founded and run by Mike Westerfield, was a key player in the history of developer tools for Apple II computers. Its first product, the ORCA/M assembler (Object Relocatable Code Assembler for Microcomputers, and also MACRO spelled backwards), developed jointly by Westerfield and Phil Montoya, was a powerful assembly language development environment, complete with a Unix-style shell, which ran on 8-bit Apple II computers.
