I purchased an old Encad SP2800 plotter, which works reasonably well. It came with several manuals, but while I have the maintenance manual, I don't have the calibration floppy disk which is required to realign the plotter after cleaning. I can't find any company able to sell me a replacement. Does anyone have one of these disks kicking around? Can some kind soul zip up the contents of the disk and e-mail it to me?
