Hi I am looking for copies of early Quantum AT drive manuals such as QUANTUM PRODRIVE 40/80AT TECHNICAL REFERENCE MANUAL, REV. A dated 10/90, or any other early Quantum Prodrive AT drive manual. I'm interested in anything up to and including the ProDrive 425AT. I have data sheets but I would like more detail on the IDE implementation. Contact me off line. Tom Gardner (650) 941-5324
