Do you think the Ox64 by Pine64 could work with Picocalc?
On the face of it, no the PINE64 Ox64 is not pin-compatible with the Raspberry Pi Pico, so it would not work with the PicoCalc. Depending on the Ox64’s capabilities, it might be possible to build an adapter board of some kind.

I just looked at the two and the Ox64 is absolutely pin compatible with the Pico. Unless you were looking at it upside down, because the usb-c port is actually on the bottom edge.
However, the Ox64 doesn’t have the same flexibility in hardware I2C and SPI pins, though, so actually talking to the keyboard and lcd might be tricky.
