I spent 5 years writing my own operating system

If you want to learn more there's a website [1] for the WRAMP architecture which goes into a fair bit of detail. The manual specifically is what students are (or at least were when I was at Waikato) given as a resource to understand it.

The toolchain and simulator are also available on GitHub [2], though it looks like the author has their own fork from an older version. A few years ago the the project was ported from a custom board to an off-the-shelf FPGA dev board and the simulator was renamed from "rexsim"/"RexSimulator" to "wsim", hence the difference in name.

Wow, I didn't know WAND had a github page. I'll get my fork merged with the main repo in that case.

The custom fork basically adds a extra button "Quick Load", since the srec file can be quite large to transfer through serial port to load, so I just implemented extra button to read srec file directly into memory.
