The olimex company just announced the: RVPC - a kit PC with a RISC-V CPU, and they say it'll cost US$1

It will support PS/2 keyboards and VGA. Intended to be a learning platform for RISC-V coding, it’s only got 2k of RAM. (I tried finding a 3rd party source for this announcement but I struck out, so I’m linking the actual olimex webpage. Not affiliated with them, just thought this looked neat.)
