<arrgh> Sometimes, the best answers are the most obvious. You may remember that, not long ago, I posted a blurb about having trouble backing up an old MFM drive in a 1990-vintage datascope. Specifically, that it's non-DOS format and on a proprietary controller. As I was copying the manuals for a different datascope this afternoon, the answer hit me like a lightning bolt, prompted by noticing that the pages I was copying at the time had to do with backing up the hard drive in a Digilog unit. "Maybe" I mused "the Interview 7500 has the same capability." Well, guess what? It did! It was not obvious because it was labeled "Copy Disk" instead of "Backup hard drive," but it most definitely allowed selecting the hard drive as the source and the floppy as the destination. Three 1.44 meg floppies later, I not only had a backup copy of the datascope's OS, but I also had it archived with Teledisk into long-term storage. The moral of the story is: If you run into a hard-drive operated datascope, or any other special device that has its own drive, never assume that said device has no backup routine of its very own! ;-) -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Owner and head honcho, Blue Feather Technologies http://www.bluefeathertech.com // E-mail: kyrrin(a)bluefeathertech.com Amateur Radio: WD6EOS since Dec.
