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.
