In this episode, Mark revives a 40-year-old speech synthesizer project based on the SP0256 chip, originally built for early home computers like the VIC-20 and Atari. After testing the original hardware with an Arduino Uno, he also explores a modern rebuild using the ESP32 and a software-based emulator, showing how vintage voice tech can still be enjoyed today with accessible tools: bit.ly/4knqGba
