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.

Whether the options were installed would not have been reflected in any labeling on the outside, including the model number. The standard cpu on the 225 was a board wtih an 8085 cpu with 64k of ram. That was the only board in the multibus cage, unless options were purchased and installed. >>> >>> Open the cardcage under the monitor and tell me what you see for multibus boards plugged in.
