Actually, tomlee59's memory is amazingly good for an event so many years ago! It's pretty much like he said. In Guide to the Macintosh Family Hardware, Apple Computer Inc., Second Edition, the SE/30 situation is detailed in the schematic on page 351. I've never done this mod but it looks like you need one dual header cable from the computer board to both internal floppies. Cut pins 9 and 20 loose on both drives. Cut the second drive pin 14 loose and drive it with the second enable from the DB-19 connector pin 17. No external floppy drive allowed in addition to the two internal ones, because the SE/30 lacks the third enable that the SE has detailed on page 340 (and that the software presumably handles at least in the SE model). Check if the SE/30 PDS may be blocked by the existing SE chassis plate, due to 96 vs 120 pin connector cutouts. [] ]'>
