[cctalk] Need Otrona Attache 8:16 MS-DOS Disk

Does anyone have a working copy of a bootable Otrona Attache MS-DOS 2.11d or 2.11e disk that they can copy and snail-mail to me? All of my disks are giving a "Bad or missing Command Interpreter" error. I no longer have another computer that reads/writes 5 1/4" IBM 360KB disks, so I need a physical copy. Please email me at feldman.r(a)comcast.net so we can arrange shipping (I am in Chicago) and payment. Thanks, Bob Feldman
