I am looking for someone familiar with the Win Systems SBC53sx single board computer for a STD bus. Need technical help and to source boards to replace defective ones in the field. Actual Win Systems product number is 400-00159-000. Have proms only and looking to port to a similar SBC53sx board 400-0151-000. This is to support a legacy design from 1992 that the customer does not have the source for.
