Emax

I figured this out yesterday and got my emax to run with the 50B as the hard drive.  Here's how:

1. the guy who sold me the emax said that it was an HD SE, but that the SE sticker had 'come off'.  I believed him because he had perfect ebay feedback, and it included the HD SE manual.  Turns out he was wrong; it was only an EMAX HD.  As someone else in this group said, you cannot use a flash card for the HD unless the emax has been updated to an SE.  or so it would seem.

2.  I tried to use both EMX and Omniflop to format a floppy disk for use in the EMAX and neither worked.  I had to format the floppy in the actual emax first, and then install the SE upgrade (with omniflop) followed by the 'plus' OS (using EMX) onto the emax-formatted floppies.  Someone said something on here about how the floppy drives in the old emaxes can go out of spec; this is what happened.  

hope this helps.
