  Hmmm, welcome aboard the sinking ship of good ole' Mitsubishi. I have
tried several times myself, with ROM ver 1.57 and the latest 1.58. So
far, the closest I've come (with the use of DRIVPARM), is the ability 
to read and write 720k disks, but due to the funny strapping on the drive,
I was unable to access my other floppy drive. (sigh). There is a 
particular type and brand I believe that works. I will try to get the name
and specs for you (and anyone else).
