  2. The Astrobe for RISC5 Windows IDE, Oberon language cross-compiler, and the Embedded Project Oberon OS are now available free of charge for the Digilent Arty, Arty-S7 and CMod-A7 FPGA development boards. This release is based on the latest Verilog RISC5 CPU and Project Oberon source code from Prof Wirth’s website. The release package now includes additional examples, Real-time clock device support and the Astrobe high-capacity HCFiler SDHC filesystem for backup and datalogging.
