I've NEVER seen a 7" color VGA display. I'd hoped I was just looking in the wrong places. > an ebay search of 7 color tv came up with a few choices. Actually, no choices. LCDs are by and large formatted for a 16:9 aspect ratio. This means that a display that's the correct width will be too narrow to properly fill the vertical space in the MPCD bezel. The original tube is still available, but the supplier wants $5000.00 for it. It's a 1:1 aspect ratio tube with a resolution of 512x512. g. -- Proud owner of F-15C 80-0007 http://www.f15sim.com - The only one of its kind.

The ASR I used in high school, and the one I bought, both had acoustic couplers that had rubber seals around both sides, and fit a Western Electric simple phone precisely. As a matter of fact, when you would remove the phone, it would make a sucking kind of 'pop' noise when the phone came out of the cradle. There was no lid involved.
