Show HN: A Project Oberon System version running on RISC-V instead of RISC-5 (github.com)

> The whole system runs on a low-cost development board (Xilinx Spartan-3 by Digilent, with 1 MB of static RAM)

If somebody wants their FPGA work to be available, they better choose MiSTer FPGA from the beginning. Costlier, but way more likely to be found around.

Would it be practical to have the ESP P4 self-host?

Love your commitment to this. You are doing excellent work to keep Wirth's computing spirit alive. Oberon's philosophy ( https://people.inf.ethz.ch/wirth/Oberon/Oberon07.Report.pdf ) is beautiful for the power it hides behind its simplicity and I wish it was a more popular language ...

Readers encountering this project for the first time should be aware that the earlier Oberon-on-RISC-V project <https://github.com/solbjorg/oberon-riscv> (HN discussion: <https://news.ycombinator.com/item?id=25497002>) exists and was already discussed on the mailing list:

what does RISC-V instead of RISC-5 mean?

I am currently exploring languages, operating systems.. my conclusions so far are that the two fish in the pond are plan9, and oberon. I am also aware of Geoff Collyers criticisms of RISC-V, and the criticisms of oberon of principia-softwarica. But that's about where my knowledge ends. I am also extremely suspicious of any project that makes any use of c++, being familiar with both the art of unix programming, and the attitudes of the suckless community.

A brief glance at https://oberon-lang.github.io/2023/12/25/towards-concurrency... tells me that oberon+ supports parallelism, so I take that to mean that the criticisms in principia-softwarica no longer completely hold, at least for that new language.

Something that really surprises me is, a project so closely connected to the simplicity and elegance of oberon, also connected to c++, a language so widely vilified for complexity and ugliness, and with which oberon itself, apparently, competes. I'm sure there must be really good reasons for all this.
