The computer named Delcon System 9x from 1994 (it's very old-school, lots of logic chips) in an industrial concrete mixer station is showing 080 or 80 on weight displays, disconnecting the weight sensor controller doesn't affect, before the discovery of the fault the station wasn't been used in a while. Does anyone knows anything about this kind of equipment and how to fix it?

Other shift found a problem with the computer itself, there was burned resistors and possibly multiple chips also, although clock generator and some of the circuit worked. It was decided to replace it with process controllers.
