Arnold's Computer History
Collection The early history of computers is in danger of being
lost as obsolete equipment is scrapped, old files are discarded and
computing pioneers submit their last jobs at the great machine room
in the sky. The information presented here is based mainly on my
personal recollections and on original material that I own. I plan to
add more when I have time. There is a lot to tell. I have also
included my collection of links to other historic computing sites on
the Internet.
