THe unit powers on and boots up to a screen asking for a boot disk. We dont have the boot disk to test this unit any further. The photos we took show the screen with black areas but this is only due to the camera. The entire screen is working properly. The unit does need some heavy cleaning and is being sold for restoration. We are not the original owners of the unit and we do not know its history. Purchase includes the computer with the power cord only. We are not accepting the returns on this purchase.
