Show HN: A Project Oberon System version running on RISC-V instead of RISC-5
Wirth continued this journey after his retirement. The sources published on projectoberon.net are written in Oberon-07, which is Wirth's last and most radical simplification of the language. There is also a free 2013 revision of the Project Oberon book available.

Opening excerpt (first ~120 words) tap to expand
This is a version of the Project Oberon System migrated from Oberon 07 to the more common Oberon 90, using a recent version of the OP2 compiler with a RISC-V (RV32) backend; the repository also includes an emulation of a machine (VM) very similar to the one described by Wirth in his Project Oberon Book, based on the well-known RV32 emulator; the latter is a stripped-down and slightly modified version with only the interpreter, combined with my own implementation of the machine and the peripherals; the memory map of Wirth's machine is reproduced 1:1 so that Kernel.Mod, Display.Mod and Input.Mod are unchanged.
