Something that can format floppies for the RX01 can effectively format RX02 floppies, too. An RX02 drive can convert RX01-formatted floppies to RX02-formatted floppies. Given how arcane the RX02 format is (sector _headers_ are written in single density; sector _data_ is written in double) I'd be pretty surprised if anything except an RX02 can do it. Noel
