Floppy controllers for MZ-700 and MZ-800

Hello,
I think somebody may help me here. I have a genuine MZ-800 and MZ-700 clone (based on CPLD) which both work fine. I built a replica of MZ Floppy disk controller MZ-1E05 with attached two 3.5 inch 720 kiB floppy drives. Hardware is working fine, i.e I can take Czech CP/M V41 disk and load something from it at 1200H (probably some boot program). No error messages. However it does not start on either MZ-700 (maybe because of 40 columns) or MZ-800 (still to figure it out).
Does anybody have a working FD configuration for MZ-700 or MZ-800 and where is a good source of boot disk images for SHARP? Any idea how to make this work?
Thanks
Alex
