I’ve installed the latest version of Ubuntu (12.04) on the old PC lab computer:
-Username, computer name and password are written on the computer itself, if needed.
-I’ve also installed on it a few of my favorite programs (LibreOffice, Inkscape, Gimp, R, Chrome).
-It boots in about 35 seconds, not bad for an “old piece of junk”!
Feel free to use it!
