Show HN: MacMind – A transformer neural network in HyperCard on a 1989 Macintosh
A developer has implemented a fully functional transformer neural network with 1,216 parameters in HyperTalk on a 1989 Macintosh, demonstrating that modern AI fundamentals are mathematically knowable rather than proprietary black boxes. This project has significant implications for AI literacy and organizational transparency—showing that the core mechanisms powering today's large language models (forward pass, backpropagation, attention) are inspectable, auditable, and runnable on legacy hardware. For IT leaders, this underscores the importance of demystifying AI systems within their organizations and investing in technical understanding of AI components to reduce vendor lock-in and build internal AI governance capabilities.
