Re: Update: Received my 50lb Datapoint 2200 computer from Austria via regular post.
Sorry for top-post - it’s the yahoo app. So the purpose of the extra screen layer is to prevent crt implosion? How did you remove it? It’s safe to remove it, as long as I don’t hit the screen with a hammer? Thanks-Steve.

They all used tubes with thick fron glass for implosion protection. Regards, Holm -- Technik Service u.

As someone pointed out, that looks like "CRT cataracts" - where the PVA layer between the face of the CRT and the implosion field breaks down. I've had to fix DEC terminals with this condition (and others here have had similar experiences on certain devices). There are ways to get the protective glass off the front. I used a wire to slice through the PVA. Others have reported using heat guns to soften the PVA. In the case of the VT220, I needed to put the glass back after cleaning both surfaces because just the CRT along wasn't thick enough to fit in the bezel with the original mounting technique. It did depend on the PVA layer. I found some 3M Silicone Tape (3M VHB Tape 4910?) that was clear and 1mm thick. I just put squares on the corners but it would likely work if you edged the entire area to keep dust out of the space between. I know DEC VT220s and VR201s are prone to this condition and I believe I've read about ADM 3A terminals with the same. Some terminals use bare CRTs (thicker face glass, or just manufactured to older standards?) -ethan

I bought one of the 110-220 converters off ePay ("Superite"). It has
performed well for me for several years.
(IBM Power5s *really* want 220 if you have both power supplies installed.
It only tells you that on page 2349134 of the manual.)

That is awesome. Looks great! Do a search on "crt cataract". There is likely a plastic cover on the CRT that is glued in place. This can be removed and cleaned. I have a Hazeltine 1500 terminal that the cataract was so bad, the plastic cover fell off. Good luck with the restoration!

Re: Update: Received my 50lb Datapoint 2200 computer from Austria via regular post.
Not only a happy shipping story, but one that involves international shipping?!?! Is that screen burn-in or something worse. I saw the photo’s before I read that line below, and my instant thought was Ew!

Found a Datapoint 2200 in Austria that I wanted - I asked seller Viktor to pack it well, by wrapping it several times in big-bubble bubbewrap, until it was just a giant cube of bubble wrap. See pics here: http://oldcomputers.net/box/ The cover was actually sent separately in another box so it didn't crushed by the 50 pound system. First, I have to rewire it from 220vac to 110vac. Second - what to do about that screen?
