In October 1991, the Laboratory started with the replacement of the old proprietary CADNETIX system hardware by SUN workstations. The Laboratory acquired: four SUN Sparcstations LPC's and four IPC's, 1.7 GBytes disk space, a 150 MB tape unit and a CDROM pack. Much effort was spent in developing interface code to drive a Gerber board drilling machine and a photo plotter to the ECAE-configuration.
In 1989, the FEL construction and manufacturing group in the former division 5 acquired a Hewlett-Packard MCAD-configuration, comprising a server, two workstations and an A1-size plotter. On this HP/UX Unix operating system, the ME10/ME30 mechanical computer assisted design package was run. In February 1991, this configuration was expanded with a fourth MCAD-station, a HP 9000-400T.
