Calculating Machine is built of Toy Parts (Aug, 1935)

This reminds me of the Tinker Toy computer built by Danny Hillis, though not quite as cool.

Calculating Machine is built of Toy Parts

CONSTRUCTED entirely from the wheels, gears and structural members of a popular construction toy set, an amazing calculating machine at Manchester University, England can do in a few minutes problems which ordinarily would require many days of tedious work by mathematicians. The only other machine of its kind is at Boston, Mass. When experiments on this machine have been completed, Mr. A. Porter and Professor Hartree, its builders, propose to make a larger model, 27 feet long and 12 feet wide.
