Show HN: Retrocomputing with Clash: Haskell for FPGA Hardware Design

I had so much fun a decade ago in University creating a game that ran on an FPGA. We were generating the RGB signals in the FPGA so we only had a little time between screen refreshes for an game logic. It was very challenging but very fun. We made a little scorched earth clone. That game worked amazingly well given the constraints of the system.

For anyone wanting to learn these systems I'd highly recommend developing a game as a learning project.

I am having trouble understanding the usefulness of all these new pseudo-HDL languages.

In all the projects that I've worked on, the choice of HDL (which was 95% of the time, Verilog, for the rest, VHDL), was never actually 'important'; the language features were never critical to the completion of the project. Verilog is fully adequate for any kind of serious HDL development.

What mattered were, the tooling, IDEs, debuggers, timing analysis tools, verification infrastructure, the IP ecosystem, etc.

Perhaps I am getting old but I just can not see how these new languages can be a serious alternative to Verilog/VHDL.

It was an interesting choice to include the Compucolor II emulation. It was a very quirky machine with some interesting design choices, but not very popular.

Ops website references https://compucolor.org, which I created. I'm glad someone was able to find something useful in it. The site has an in-browser javascript emulation of the Compucolor II. I've written one javascript program in my life, and that emulator is it. It has languished since 2014 other than a bug fix here and there. Eventually I'll refresh the code, and hopefully replace the display generation logic with webgl.

The core emulator was quite simple to write, but 90% of the time was spent getting the code to work across browsers and dealing with the infuriating differences in keyboard handling. Maybe things are better now.
