Thanks for the YouTube link. I particularly like the nostalgic last few minutes. It raised two questions about the 23GP22 CRT:
1. Was Motorola the company that designed and produced the first 23GP22s?
2. Why did the 23GP22 have such a short service life? Were the electron guns of inferior design/quality? Did the phosphors require so much drive that the electron guns just didn't last long?
