Cardputer uLisp Machine

The Cardputer uLisp Machine, a handheld Lisp computer with a self-contained keyboard and display.
The M5Stack Cardputer is a card-sized portable computer based on the ESP32-S3, available for about £30/$30. It has a 240x135 colour TFT display that gives a scrolling display of up to 16 lines of 40 characters, an integrated 56-key keyboard, and an SD card socket. It's available direct from M5Stack [1], or from The Pi-Hut in the UK [2].
