Many years ago, I had a C.Itoh CIT-101, which is basically a VT100 clone.
Bought it from a local university; they have a "surplus goods" shop which used to funnel all sorts of fun computer stuff, but the last ~5 years, they've switched to selling the computers by the palet-load at auction instead.
I used it briefly as an auxillary display for a Linux box (set up to display top), and when trying to bootstrap a Sun Ultra 10 without the standard keyboard//mouse).
Eventually put it out because, honestly, it was big and clunky and achieved no useful goal that couldn't be done with a small old laptop running terminal-emulator software.
