The text discusses the development of a Neo4j client for the Commodore 64, an old home computer. The author, Director of Engineering at Neo4j, aimed to create a client that could run on the limited hardware and learn about the Bolt protocol, which is used by Neo4j. The project required implementing a TCP/IP stack, a network card emulator, and a custom input routine due to the lack of support for scanf() in the CC65 compiler. The author also implemented a Cypher shell client with basic authentication and only supports unencrypted communication. The code is written in C using the CC65 compiler and IP65 library, which provides TCP/IP functionality. The project demonstrates the challenges of working with limited hardware resources and the importance of understanding low-level protocols like Bolt.
