Afterwards they scaled this process up to make the 11-inch storage CRT for the 4010 terminal ($5000) and eventually a 26 inch storage CRT for the 4016 terminal ($12,000)! The storage tubes only lasted about 5000 screens worth, by then the screen was majorly degraded with about half the area dropping out. so each displayed graphic image cost you $1 to $2.50 each!!
I use their oscilloscopes for many years, when I was employed by the top Communication company in the world at the time. I found them to be the best, oscilloscopes available. I wish I still own one today.
