The machine is a Narrow Body cabinet. The glass will only fit the narrow cabinets.
The power supply is a Narrow Body Power Supply.
Most all other parts, hopper, board, reels, will fit all Uni's that use the 8116 or 8800 board.
If the power supply does not work, open it up and check that voltage regulator that sits on the bottom of the power supply. It has long legs that press against two solder caps.
I've found the solder cap can crack and break off.
Also, the model is not V90, it should be a Y90. And even though it is stamped next to "Model No.", it really is year of manufacture, 1990. Universal was required to stamp year of manufacture and their name plate had no place for date so they stamped it next to Model. Why, because they didn't have a model number either!
