Assembly Code and the Assembler

The assembly language and assembler used in this demonstration are versions of that which is used in the textbook "An Invitation to Computer Science" by G. Michael Schneider and Judith L. Gersting, PWS Publishing, Pacific Grove CA, 1998. Chapter 5. An emulator for the machine language is also available.

Note: Because of the limitations on the available storage in the assembler and machine language emulators the instruction formats are limited to 4 bits for both the operation code and the address:
