what i did is use an old Pentium 3 PC with both a 5 1/4" and 3.5" floppy drives loaded cp/m-86 and ran dskmaint.cmd made a copy of all the software disks from the b: drive to the a: drive.
Then one by one i loaded the disks on a more modern system through a USB floppy drive and made .img files of the disks using winrar.exe
when the images are copied on blank floppies, & then rebooted on a machine with a 3.5 floppy drive they will run.
