|

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
