In September 1956 IBM launched the 305 RAMAC, the first computer with a hard
disk drive(HDD). The HDD weighed over a ton and stored 5MB of data.
That's not a typo ..... 5MB of data.

I built a computer that did addition in the fifth grade, it was not
nearly that big.

I built a working nuclear cloud chamber for my 7th grade science
project. It worked perfectly. Damned thing incorporated a spark coil
from a Model A Ford.


I take it you don't beleive me, no problem, I don't really think I
have a credibility problem here Me and dad built it on a piece of
plywood with some wooden "T's". It was really suited better for a game
where you get to slide marbles down the chute in ones, twos, or
threes. The idea is to leave your opponent with the last T to turn...
But it was a computer in all practiacl purposes, it worked by switches
being either on or off as it were...



I believe you. I also put together some switch operated computers. I
also built a working cloud chamber in the 7th grade and could provide
you with the details, although there is one detail I cannot recall
precisely. It was, after all, quite a while ago.
