Effusive regards if you have not readed this thread:
http://enterpriseforever.com/other-topics/hello-from-spain/ I've gotten a HxC Floppy Emulator and put it on top of the EXDOS controller you built me long ago(thanks!). Even I powered it from the expansion card, and it looks much better than with the necessary PSU.
I have tried all combinations, works perfect with simulation of a: and real floppy en b:(PC), but as I don't have nor need phisic disks I opted by simulate the two readers.
The only problem is with your HXC prog., that put the floppy emulator in direct access mode but fills the screen with zeros and hangs.
I've followed strictly your directions(or limitations) but don't know why it happens.
The firmware version is V1.8.2.40. I received the emulator in January 2014.
