There’s now full information about setting up and using the PicoCalc handheld computer from Clockwork Pi as a self-contained Lisp Machine based on the latest release of uLisp:
It incorporates an RP2040-based Raspberry Pi Pico board (supplied), but you can swap this for a RP2350-based Raspberry Pi Pico 2 board, their Wi-Fi versions, or any other compatible board.
It has a 320x320 4" colour IPS display that gives a scrolling display of 32 lines of 53 characters, a backlit QWERTY keyboard, and an SD card socket. It’s powered by one or optionally two 18650 rechargeable lithium batteries (not supplied), and these can be charged via the PicoCalc USB-C port.
