For what it's worth, I have the manual for the DSD880... I can say for a fact that it is like Jerome described, a big honkin' box with an 8 inch floppy and a Shugart 10MB 8" disk drive, as well as custom microcoded logic... The DSD440 is similar, but the one I had contained 2 8" FDD's and a board covered in Intel 3000 series bitslice logic... So I do indeed doubt that it could control anything else.. I do have another board that I want to get rid of, with manual, that I seem to recall will control 5.25" floppies, e-mail me if you might be interested, Sergio. I don't mind shipping it across the water ;p Will J _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com/intl.asp
