Software Tools for ByteFrost - A Breadboard 8-Bit Computer
Be sure to check out the YouTube channel for more in-depth explanations of how the ByteFrost works!
In this Github repository are software tools for using the ByteFrost computer:
Note: The Assembler/ directory contains the deprecated assembler; Assembler V2/ contains the new assembler, which also has new preprocessing features, assembly instructions that can be translated to multiple ISA instructions, and support for the new 16-bit memory address space expansion.
