This seemed to be for an appletalk:SCSI interface, but I'm sure a SCSI:appletalk interface would work even better, given the relative transfer rates. A packet-radio controller on SCSI might also suit this device well. -adrian -- -------------------------------------------------------------------------- Adrian Godwin (agodwin@acorn.co.uk)
