SE/30 - Junk item. The fan spins when connected to power, but nothing appears on the screen. The unit is generally discolored from sun exposure. The mouse, in particular, is severely discolored, having turned brown. I believe the expansion card is a video card. I haven't checked the internal components due to lack of tools. This item is over 30 years old, so no warranty can be provided. Sold as-is, no returns accepted. Included items: Power cable Keyboard Keyboard cable Mouse Thank you for viewing.
