Emax

Ok...LOL. Well it's truly not Schugart and it's not PC either. 

Simply having Addresses on a drive does not make it Schugart standard. 

There were only just a few keyboards that ever even used a real Shugart standard 3.5 drive.

Emax was way to new to use that dated tech.

Rish

Life is like MIDI, your either IN, OUT or THRU.
