through doing the programming the hard way . The thing was that weren’t a lot of
textbooks around at the time so there was a great emphasis on not just telling you
the theory but also telling you the potholes that they’d fallen down
so you too
could avoid them."

"Well, the first technology of 1948 was valves. And it was steadily moving into the
transistor era and the first integrated circuits were just coming out around then. It
was a time of real technological change going from valves into much smaller units
and circuits so that machines could be built in a much smaller space."

"That was the Atlas machine and again that was a transistor machine which was
fairly advanced at the time and it had a lot of very sophisticated facilities
compared with the 1948 machine which was really only the power of your average
small hand held computer."

"If you imagine a very large lounge-cum-dining room and you imagine that were
down both sides of the walls down the long sides of the walls. And looms of
cables strung across the two cabinets down the sides between them, you’ll get the
sort of feeling of how big the whole thing was."

"It’s a replica of the world’s first computer – it’s a rebuild – a very good rebuild and
the person who’s done the rebuilding Chris Burton has had to go right round the
country to find all the bits and pieces."

"The fundamental principles of going to execute instructions one after another
until you come to something where you want to jump are still very much the same.
So, although the technology has changed a great deal, the underlying principles
are very much as they always were. Of course, things are lot more sophisticated
now and we’re able to do more things but when you look at it… it all stems from
the 1948 machine.
I hope that the message that they take away is that we’ve come a long away and
there’s still a long way to go. And that it’s an exciting topic to be in."
