EMMATRONIC disk copy?

Does anyone know a computer called EMMATRONIC? It was used as a control computer for knitting machines some 15-20 years ago, the mechanics of the knitting machines are running fine, but now there is only one reliable system/program disk left. The maker of the knitting machines is out of business some time ago and so will the knitting machines soon be if I can not make the owner a backup copy of the disk! I have been told it's some sort of Apple II for the European market but then again I might be totally wrong. I need to copy a 5.25" disk for this system, the format is unknown and unfortunately the disk is known to be protected somehow (at least the EMMATRONIC refuses to copy it) and also I have no working Apples. Any ideas/suggestions? thanks in advance. -------------------------------------------------------------------- Thorhallur Ragnarsson Electronics Technician Bjarmastig 1 Verkmenntaskolinn Akureyri IS-600 AKUREYRI Box 280 Iceland IS-602 AKUREYRI E-Mail: thorh(a)ismennt.is Iceland --------------------------------------------------------------------
