This is a Zenith Data systems 486 computer.
The case is fairly clean, the power supply works, the lights come on on the front, and the hard drive spins up. It will not display.

The battery appears to have leaked a bit, (see photos) this may be the cause.

I believe this one may be repairable so I did not strip it down, the CPU, memory and drives are included.
