The 8254 is a peripheral chip for a microprocessor. Did you locate one? Are there other peripheral chips for that microprocessor? Can it be that the WD-chips were engineering samples that never made it into regular production? Where did you find the boards? What are the connectors on the board like? ... The more info you provide the more people can help you.
