Same here, but 27C010 and 27C256 have basically the same pins, except the 2 additional address lines. I built a simple adapter board which includes DIP switches to toggle A15 and A16. This way I can program the chips in 4 parts. Marcel _______________________________________________ QL-Users Mailing List _______________________________________________ QL-Users Mailing List
