If I remember correctly, when you create a new program, the first question is asked is Mazatrol or EIA. Try creating a new program and see if the menu keys below the CRT ask this question. Also, in the maintenance screen there is a menu key for options or machine spec. This may show if EIA is on.
Unfortunately you cannot hook up a floppy such as one on your PC. Other then a CMT which has a floppy on it. Mazak has special software for Mazatrol. Try Griffo Brothers though, they may have what your looking for though.
Others on the forum may have more information to your questions though.
