Manufacturer: Hisoft SCSI-2 module that uses the PCMCIA slot on the A600 and A1200. It is quite safe to hot plug the squirrel, that is to remove it and connect it whilst the machine is turned on. It is not currently possible to Autoboot or Automount hard drives connected to the surf squirrel however it does use Commodore RDB standards and is compatible with almost all SCSI devices.
