The ClockworkPi DevTerm (A0604 Model) is a Rockchip RK3399-based computer designed for tinkerers and retro-computation fans. It's initially launched with a spin of Armbian but I worked on porting Manjaro ARM (a derivative of ArchLinux ARM) to the device to get it running closer to mainline kernels and newer software. It's now available as a supported device in Manjaro ARM, roughly with parity to the Armbian-based "ClockworkOS".
Work to cleanup the vendor-provided patchsets and get them accepted upstream stalled out, but the Manjaro ARM team continues to maintain support for it, and I occasionally update patches to fix issues with newer kernel versions.
