Zoscii – Quantum-proof comms without encryption

ZOSCII Zero Overhead Secure Coding Information Interchange.

An innovative character encoding system that eliminates lookup table overhead while providing built-in security properties through direct memory addressing.

CyborgZOSCII is an alternative to ASCII/PETSCII that uses direct ROM addressing instead of traditional character-to-value mapping. This approach provides significant advantages for resource-constrained systems while offering unique security properties.

1. Zero ROM overhead - No lookup tables required (ASCII/PETSCII tables eliminated)
2. Faster execution - Direct addressing eliminates base+offset calculations and even open to stack abuse for fast text printing
3. Perfect for 8-bit systems - Optimized for systems where every CPU cycle matters

3. Zero cryptography, maximum security - 100% secure when reference ROM unknown
4. Fault tolerance - ROM corruption causes typos, not total failure
5. No traditional cipher vulnerabilities - Uses addressing, not mathematical transformations

• Uses 16-bit addresses per character (vs 8-bit character codes)
• Characters reference direct ROM memory locations
• Same message generates different encodings each time (random address selection)
• No mathematical operations required for decoding
