It reads all 1's when a disk is in, and all 0's when no disk implying 1) standard 80tk disk and 0) no drive. You'll probably have to kludge a circuit to return alternating 1's and 0's so it recognizes it as a 40tk., or do something about the rdy line. -- "What is a DJ if he can't scratch?" - Uncle Jamms Army The views expressed are those of the author, and not of Visual Edge, nor Usenet.
