Ritter's Heirloom #vi is in #FreeBSD ports today, coming from the same place that it has for a long time.

https://freshports.org/editors/2bsd-vi/

It was dropped from #ArchLinux because it did not compile and hadn't changed in 20 years. Ironically, this is because the (GNU) C language had changed, and it has to nowadays be compiled forcing an older GNU C language version.

Several people have independently discovered the Makefile patch that gets it to build on #Debian and the like.

STEVIE was posted to comp.sources.unix in 1988:

Unfortunately, Sven Guckes's vi Clones WWW site was never completed with some of this, notably lacking Heirloom vi, for example.

But it does mention oft-overlooked commercial clones such as Watcom's vi, a from-scratch implementation started in 1983 that is also now source-available:
