Does anyone have the pinout (or a datasheet) for the SED9421 chip (18 pin DIL package). I think it's some kind of floppy disk data seperator/PLL. A web search has found nothing of obvious use... If you want to send me anything other than plain text (like an image, or a pdf), please don't send it here. Please send it to tony_duell at yahoo.co.uk -tony
