8" floppy drive for PC, RS/6000, 68k Mac or Alpha

I want one. I can use a PCI, ISA, EISA, MCA (PS/2 or RS/6k), NuBus or QBus adapter. The main requirement is that hardware + software be able to low-level format disks to RX02. I have a YE Data YD-180 drive from an AS/400 that looks brand new. According to a couple of comp.os.cpm posts, it's a standard interface DSDD 1.2MB drive with DC24V/DC5V input. So far so good, and I have a couple of older ISA floppy controllers that should talk to it (right?), but I need a controller cable and power pinout for it. For that matter, between the DE9 power connector on the IBM sled and the power input on the drive itself, there's a small PDB that looks like it might be a transformer or step-down. Anybody know what voltage the AS/400 feeds it? Anybody happen to have an 8" enclosure and PSU they don't want? And, most importantly, that drive *will* format a disk as IBM 3740 format, right? I have 3 computers with RX02 drives, about 300 bulk-erased floppies, and no way to make the floppies useful in those drives*, and that's starting to p_ss me off. * a couple of places I can trade degaussed disks for formatted at varying ratios, and that's probably the cheapest way to go, but that's hardly the point, right?
