 The terminals are models UTS20, UTS30, UTS40, UTS50 and SVT1120,
 however only the UTS20 is dumped (program roms only).

+There were other terminals (Uniscope 100/200/300/400) and UTS60, but
+they had different hardware. Uniscope models are believed to use the i8080,
+and the UTS60 was a colour graphics terminal with a MC68000 and 2 floppy drives.
 
 The terminal has 2 screens selectable by the operator with the Fn + 1-2
 buttons. Thus the user can have two sessions open at once, to different
