The Rainbow uses 80 track (96 tpi) Single sidded double density floppy drives. IBM PCs use 40 track(48tpi) Double Sidded Double Density. However PC DOS can format a 48tpi frive as single sidded using the format/1s option, these disks can be read and written to by the rainbow with out any additional software. The rainbow can not format/read or write any double sidded disk. Ed
