Emax

I have just bought an Emax (not sure if its the Emax 1?) but it just 
has the Emax "signature" style logo going up across the top not the 
big pink EMAX II lettering..... (sorry i know there have been loads 
of different Emax versions!!)

Anyway is there an operating system disk avliable to turn my Emax 
into and Emax SE - or even an Emax II?

Emax SE would be fine - what were the differences? ALso could anyone 
direct me to a website etc? were i could download this onto floppy 
for my new machine?

Please help!
