As noted, in another reply, the DEC VT-5xx terminal series was mfg. by ADDS.

Unfortunately, when I plug it in and push the power switch, nothing happens. Rather than just open it up and poke, I was hoping others here might have some experience with that model. Are the schematics anywhere? Not on Bitsavers as far as I can see. Are other terminals at all similar? The newest schematic I see is for the VT340. It would be nice to get the terminal working again. Alternatively, a wild idea would be to use the CRT in place of the "screen fungus" infested VR201 CRT I would like to repair. Any chance of that working? paul
