Backed up from a local Blogger export (114020545086461187/114020545086461187.html) on 2026-01-01.
Recently some real relics of the early software age have been seeing the light of day:
VisiCalc for DOS 1.0: http://www.bricklin.com/history/vcexecutable.htm
Borlands first series of compilers: http://community.borland.com/museum/
And my favorite, some of first C compiler sources: http://www.cs.bell-labs.com/who/dmr/primevalC.html
So many good tidbits in this last article.
