This is the second video in my serious on the Burroughs B21 / Convergent Technologies AWS computer. In the first video, I got the computer working, but the screen was largely unreadable due to "monitor cataract". Monitor cataracts are a breakdown of the PVA adhesive between the CRT tube and the safety glass that is in front of the CRT. This can render a monitor unreadable due to the distortion. I have never performed this procedure before and was a bit apprehensive, but with some suggestions and encouragement from others online, I successfully repaired my monitor. In addition to the repair, I go over some of the tools I used. Finally, I do a short demo of the Burroughs / Convergent computer, now that we can clearly read the screen.
