It seems computers without an Arm or x86 chip are in serious demand in the RISC-V community.
A Raspberry Pi-like small-board computer with an RISC-V chip and GPU went up for preorder on Alibaba two days ago, but is now listed as being no longer available.
The system was announced by the Chinese hardware firm Sipeed on Twitter page on Oct. 12. A later tweet by the company noted that only 80 boards were available, and would ship in a month.
