laptops and 5.25 inch floppy drives?

ImageDisk controls (and expects) a 765 family diskette controller directly - via corresponding hardware I/O addresses, DMA channels and interrupts - This is necessary in order to be able to analize, read and write non-DOS format disks. It will *NOT* communicate with a "smart" device connected via USB or any other non-765 interface - it would be quite likely that such a device would not be able to understand non-FAT formats, formats where the sector size is not 512, formats where sectors are not numbered 1-(expected number for media), or sector/head numbers recorded on the disk don't correspond to what PCs think they should be.... I have a Eurocom laptop with a connecter to which connects an external 5.25" drive enclosure - this appears as a standard floppy drive connected via the FDC - such an arrangement should work OK with ImageDisk - I'm pretty sure there are other older laptops with similar external drive schemes.
