MacMind is a complete transformer neural network implemented in HyperTalk, running on a 1989 Macintosh SE/30 with 1,216 parameters. The project demonstrates that neural networks—forward pass, backpropagation, attention—are mathematical fundamentals, not magic, executable on any hardware from a 35-year-old processor to modern GPUs.

Show HN: MacMind – A transformer neural network in HyperCard on a 1989 Macintosh
MacMind implements a complete transformer with 1,216 parameters in HyperTalk on a 1989 Macintosh SE/30, proving neural networks are portable mathematical abstractions independent of hardware generation.
