Hi
It looks like it might need a little work.
The large board attached to the back of the unit
is called the IOC board. It is just a terminal board for the
keyboard/video. It also has various I/O such as the
single density disk controller. It has a 8085 on it
as well to run the terminal.
It doesn't look like it is working correctly.
It will need some trouble shooting.
First check the voltages.
Just curious, what boards do you have in
the UPP. There should be three boards in it.
The rear one is the controller and the two towards
the from are the personality cards.
