Scope and content
This card, based on a "4 slot DEC module", arbitrated the access priority of 15 datalinks of a CERNET node. Each datalinks could transfer data full duplex at 2.5 Mbit/sec over 1 Km of twisted pair (POD) cable. This was the frontier technology in 1980. The modest amount of integrated circuits was compensated by printing on the board photographs of the hardware designers, whose Belgian, Dutch and French nationality was underlined by the the short poem.
