Hi there!
My team found this computer in an old school and listed it on our Etsy site:

We'd love to be able to test it, but have no idea how to! We've figured out it's missing a monitor and some kind of control for the games. Any advice or tips would be great! We'd love to sell this to someone in the best condition we can.

From the pics I can see that you have the power supply and you also have the RF modulator. What you will need to test it is a TV with an analogue antenna input. If everything works you should be able to tune the TV into the channel that the RF modulator is set up for. Prior to using the power supply on the computer I would recommend checking the DC voltage output on it.

With one of these adapters you can connect the output of the RF modulator to the antenna jack of a TV, and then tune the TV to analog channel 3 or 4 (depending on what the modulator is set to).
