Speaking of oddball terminals, does anyone have details on Cybernex APL-100 terminals? 
I acquired one a couple of years ago and have had no luck locating documentation for them.

I'll try to describe it as best I can, based on old memory. I could have sworn that it had a dataplate label identifying it as a DEC VT02, but that could be way off the mark.

I don't recall the model number of the display, but I might recognize one if I saw it. It was quite long, making the whole terminal quite long. It had X, Y and Z BNC inputs, and it had a neat test mode that drew a spiral on the screen.

I don't think that the Flip Chip boards were still in it when I got it, but it came along with a small box of spare Flip Chips.

The lower chassis and the top cover were painted approximately white as I recall.

The display was most likely a Tektronix 611. DEC used them with their 
point plot display systems like the VC8E.
