My first job at Tektronix was on the 4025 GAT-II (Great American Terminal) project.  This was the first Tektronix video (i.e. non-DVST) graphics terminal.  My job previous to Tektronix while in school was a stonecutter at Olympia Monument Works.  I cut granite and really enjoyed the craftsmanship of the work.  This was before computers so everything was hand drawn and hand cut.  I decided to cut a stone for the project and presented it to the project leader Stan Davis.  Many years after Stan left Tektronix he brought by his stone so I could get these pictures.

At the time I cut this stone we did not have an operational prototype so I didn't realize the phosphor was P-39 green!

And a real 4025.
