Faith in the Acorn Electron waxes strong in Cumana's breast - the disk specialist, which became an Electron distributor just before Acorn ran aground, has now released an alternative disk interface for the same machine.

The unit plugs into an Electron Plus One expansion module, and you can use it with either 5.25" or 3.5" disk drives and 40 or 80 track disks. There are utilities supplied with the device to let you copy files between Cumana and Acorn DFS systems, with other options available. The interface costs £149.
