Dear Joerg, > By definition, Project Oberon works on the imaginary RISCv5. > NW emulated his RISCv5 on an FPGA HW > PdW emulated the RISCv5 in C and SDL on arbiträry HW > > Short: Project Oberon is ALWAYS emulated as there is no real RISCv5 HW. That's rubbish. The RISC5 is implemented in hardware. Thanks, Paul
