I'm sure its very intersting.
The website is designed for domestic consumption only as its all in Danish.

I had the privilege of visiting what Nico calls a

yesterday evening, and it is far more than most of what I've seen!
They have a very substantial collection of all sorts of systems,
peripherals and documentation, including a GIER from ca. 1962 that I saw
(and
heard) run.
As a debugging/operations aid, they had attached
the overflow bit to a
speaker so it could generate 1-bit sound - one demo they gave me was a
program to calculate e that played a sound for each iteration so you
could hear the steady progress. But of course if there is a sound
output, no one can avoid playing with it. There were numerous pieces
of computationally generated music composed for the machine (on paper
tape), but also a program for playing a recorded, real-life sound in 1-bit
audio!
The collection includes numerous other computers including pretty much
the entire RC line, as well as pre-computer tabulators, keypunches,
paper handling machine and the like. The artifacts are well-ordered
and in large part well labeled for even the uninitiated visitor.
Everything is laid out quite thoughtfully, with wide aisles, in a
large, well-lit basement. There are interpretive displays here and
there, as well as a small but appealing lecture/display area.
The datamuseum.dk collection represents 25 years of accumulation, I
was told. But more importantly, I think their work demonstrates a
very well-considered approach for presenting the history of the
collection's machines to visitors.
My hosts were also warm and wonderful people who clearly love what
they do and enjoy sharing it. They made me feel among friends, if not
family. :-)
Thanks, Finn and everyone else (sorry, I'm bad with names), for
sharing your time and your passion with me! -- Ian
