Furyband is an old-school Angband variant that I built off of ToME.
I’ve placed the last version I’ve done with the source code here. I’ve not done any updates or patches on it in years, so YMMV.
Zop is the current maintainer and has been patching/updating the codebase, and has it hosted on GitHub.
There are forums on Anband.oook.CZ.
