On the on ship's Ethernet coaxial backbone we established a network of computers for swath bathymetry and general purpose data processing, as shown by Fig. 8. Among them, PC's running Linux and Windows OS, and two SUN ULTRA 1 workstations running Solaris 2.5 and 2.7 OS. The SUN WS were devoted to multibeam data processing, whilst the LINUX WS were used for NFS disk and printer spooling services. The ship's HP Mod. 750 A0 color ink-jet plotter was used for charting.
During the 60 days cruise, we can report just a few stops of some machines, that recovered smoothly after the reboot or file system check.

Editing of the data was performed with the NEPTUNE package, and gridded and countoured with the IRAP software. Several maps at scales ranging from 1:50000 to 1:500000 were reproduced on board utilizing GMT, IGM's Plotmap software (Ligi and Bortoluzzi, 1989) and AUTOCAD.
