The BASIC Issue With Retro Computers

If you are interested in how a computer works at the hardware grass-roots level, past all the hardware and software abstractions intended to make them easier to use, you can sometimes find yourself frustrated in your investigations. Desktop and laptop computers are black boxes both physically and figuratively, and microcontrollers have retreated into their packages behind all the built-in peripherals that make them into systems-on-chips.

BASIC Interpreter Hidden In ESP32 Silicon

We’ve been keeping up with the ongoing software developed for the ESP32 WiFi chip, and that means a lot of flashing, hooking up random wires, and rebooting. Along the way, we stumbled on an Easter egg: the ESP32 processor has a built-in BASIC interpreter to fall back on.

That’s a cool little hack to find, but we couldn’t find some crucial functions that would have made it a lot more useful. Still, it’s great fun to play around in real-time with the chip. And you’ll absolutely get an LED blinking faster in ESP32 BASIC than you will on an Arduino!
