Hello all, i'm new here so please go easy on me.. i have been given an etching machine that is programmed from a simple dos application, i have the orignal software disk but when you run it, it asks for the dongle to be fitted. this was not supplied. Can any one help me by looking at the program and seeing if this can be bypassed, it would be a shame to throw the machine away because of a poxy dongle. any help will be great. many thanks Carlsburg.
