Try Word Unperfect
Current binary
The main public test build is a Linux x86_64 host package. It starts in the WordPerfect-style full TUI by default and uses libc-hosted input/output paths rather than DOS calls. This build includes the current Block menu, arrow-key submenu navigation, console mouse menu coverage, and refreshed font attribute rendering.
