    The Oberon channel has several videos of Oberon in action,

    While Oberon was quite cool, people should also learn about its Xerox influence,

    "Eric Bier Demonstrates Cedar"

    https://www.youtube.com/watch?v=z_dt7NG38V4

    Also dive into what happened afterwards, Oberon-2, Active Oberon, Zonnon,...

    Active Oberon could be considered quite modern, also makes the distinction between safe and unsafe pointers, which improves the experience for low level coding.

    https://github.com/metacore/A2OS

    One of the best things about these systems is proving what systems programming with automatic memory management were capable of.

    Given Oberon-2's influence on Go, maybe improving Fyne (https://fyne.io/fynedesk/) with something like gRPC for the dynamic experience, could be a possible sucessor.

  • WorkOS

    The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.

  • Oberon_SDRAM

    Oberon core for FleaFPGA Ohm board

    This project is still a great example of a complete computer design, starting from Niklaus Wirth's own RISC5 CPU (not a RISC-V) and very simple peripherals over the OS, runtime/garbage collector, compiler, GUI and simple example applications.

    One problem of the original implementation is that it was based on an old Xilinx Spartan 3 development board. This is not only no longer available, but it is one of the few FPGA boards that used 32 bit wide fast (12 ns IIRC) asynchronous SRAM chips. Wirth's hardware design relies heavily on this.

    Some years ago, there was a compatible board, the OberonStation. However, it seems this is no longer manufactures: https://pcper.com/2015/12/meet-the-oberonstation-kid-friendl...

    However, some modified designs exist that implement a cache in FPGA block RAM and an SDRAM controller. These can be used one more recent FPGA boards:

    - FleaFPGA "Ohm" board with a Lattice ECP5 FPGA and 32 MB RAM (https://fleasystems.com/fleaFPGA_Ohm.html) - https://github.com/Basman74/Oberon_SDRAM

    - Radiona ulx3s, another ECP5 in an open source design (https://github.com/emard/oberon) - https://github.com/emard/oberon

    - PapilioPro using a Xilinx Spartan 6 LX, another open source PCB design (https://papilio.cc/index.php?n=Papilio.PapilioPro) - https://opencores.org/projects/oberon_sdram

    Shameless plug: my student Rikke's port of Project Oberon to RV32I (this is a real RISC-V), however, we still need to find some time to build an FPGA-based SoC. Currently, it runs in emulation: https://github.com/solbjorg/oberon-riscv

  • oberon-riscv

    Oberon RISC-V port, based on Samuel Falvo's RISC-V compiler and Peter de Wachter's Project Norebo. Part of an academic project to evaluate Project Oberon on RISC-V.

  • THM-Oberon

    This should be possible - Hellwig Geisse (forgot to mention his project, sorry - https://github.com/hgeisse/THM-Oberon) is working on an Oberon port to the Terasic DE2-115 FPGA port, which also an Altera FPGA like the MiSTer. The basis of the MiSTer is a Terasic DE10 Nano FPGA board, which has a more recent Cyclone V FPGA (the DE2-115 has a Cyclone II).

    The MiST (MiSTer's predecessor, https://github.com/mist-devel) would also be a nice platform.
