I believe that without the full EPP in effect, the port has some pins that are write only, and some that read only. IIRC the readable pins in the other modes only add up to 5 (a normal printers status bits), but I'd expect the mesa boards need a full 8 bits going both ways, and only the EPP mode can do that. Peter W. can clarify that if I'm full of it since IIRC those boards are his. :) Better it comes straight from the person who knows for sure.
