After the IBM-PC birthday, now the LINUX's one.
I remember going to the university to get LINUX (as it was too big to get it
with a mere 33.6K modem) I used to grab the Slackware distribution packaged with 3"1/2 floppies.
HAPPY BIRTHDAY LINUX and LONG LIFE TO YOU !!!
(I have no doubt about it as we can find it on Mobile, TV, STB, etc.)
