Sylvania's MOBIDIC, short for "MOBIle DIgital Computer", was a transistorized computer intended to store, sort and route information as one part of the United States Army's Fieldata concept.
Several FIELDATA-standard computers were built during the lifetime of the project, including the transportable MOBIDIC from Sylvania, and the BASICPAC and LOGICPAC from Philco.

Magnetic-core memory

Machines were normally equipped with two parallel banks of core memory with 4096 words each, but was expandable to seven banks maximum.
A notable example was the portable (truck-based) MOBIDIC computer developed by Sylvania for the United States Army Signal Corps in the late 1950s.
