This is the oldest version of this code I could find, mostly of historical interest. I'd suggest to archive it here as well.

I think the original author (whose name has changed) and a few very early contributors mentioned there deserve special mention in AUTHORS.md - this was before the license change, and me becoming the maintainer of the Linux port in 1995. Oldest copyright notices date back to 1988, older than the Linux kernel.
