It is also possible to add the Mitsumi devices to an Iyonix. Some models of Iyonix now come with the floppy/card readers supplied.
As part of the Iyonix downunder project
we fitted Mitsumi FA404-A drives (USB2)
and have only had to edit a command to check for this on startup as it caused a timing problem. Now all we have to do is double click on a module kept in the Apps folder until Castle release the updated USB drivers. Will Ling helped to locate the problem and suggested the interim solution.
