There is no way to low-level format disks on a DEC RX01 or RX02. The hardware doesn't support it in the controller inside the DEC disk drive. DEC expected you to buy media from them.
Not really. You can use any standard 3740 formatted disk (i.e. 26 sectors/track, 128 bytes/sector, 77 tracks, FM) and change it to RX02 formatting in an RX02 drive with
.FORMAT DY0: or change it back to RX01 with .FORMAT/SINGLEDENSITY DY0: In both cases you need to .INIT/BAD DY0: to create the directory.
You could also clone a formatted double-density disks with a flux-level reader/writer board.
Only a /slight/ overkill... Christian
