The nameplate from the first electronic (vacuum-tube based) digital computer used at CRNL. The computer, acquired in 1957 was known by various names, the Datatron, the Burroughs 205 or the Electrodata 205 and consisted of a large (~ 3 m long) cabinet containing a data entry panel, a large number of plug-in, electron-tube based modules and a large memory drum. It also had a separate motor-generator unit to supply the power required. The nameplate, which identifies the CRNL unit as having Serial Number 149, was removed from the mainframe which has been sitting neglected outdoors near a collector’s storage sheds since the early 1960s. The aluminum plate measures 11 cm by 8 cm.
