Hard drive adapters

Does anyone out there know of some sort of gizmo that could be made that would convert an old RLL or MFM Hard drive to be used with a parallel interface? I've seen then for IDE, but that's it. I've got a couple of old HD's laying around that I'd like to put to use, but there's no room in any of my computers to put them. By the way, does anyone have any old Apple or TRS-80 external disk drives that they'd want to get rid of for a few bucks? I don't need the drive itself. I need the case and power supply and that's it. If they're TRS-80, I could use the drive itself, too. I'm also looking for disk-based (and tape-based) software for the TRS-80 Model III. I'm especially looking for the TRS-DOS operating system for it (floppy got ran over by an office chair *cringe*). -- -Jason (roblwill(a)usaor.net) ICQ#-1730318
