Geek art: A miniature diorama of an IBM 370 data processing center.
It had a much nicer design and color scheme than the 360, and it did away with the banks and banks of switches. I decided that I wanted to capture it in miniature. At the time, I didn't have a ruler, so I took the measurements in computer cards, and took it home and punched the numbers into a calculator to get the correct dimensions.
