I have an older 286 I've been restoring and decided not to fool around with trying to find and keep running, an MFM drive. I have an interface card that has both FD and HD interfaces, but I can't, even from the manual, determine what kind of interface it has for the HD. All I know is it is 40 pin and the manual says not to use and ST412/506 drive and only use an "AT bus" hard disk. I thought it would be and IDE, but why wouldn't they call it that. Also, the pinout in the manual doesn't match IDE. So my question is, was there another drive interface before IDE that used a single 40 pin cable?
