Here is a timeline of Digital Equipment Corporation [DEC] with some great pictures of their back-catalog. That last picture shows one of their VT100 video terminals, which is the same one used by NED. I bought one of those years ago on ebay for next to nothing just in case I ever pick up a Synclavier ii, or maybe if I figure out a way of running it with my PSMT
Below is a stock picture of the PSMT and a track I made on one, from my album Twenty Systems
