DIODE LOGIC CIRCUITS

DIODE LOGIC CIRCUITS. International Business Machines Corp. 1880 ft., b&w, 16 mm

Registration MU66 Uncertain

Term began: 1959-03-02
Claimant: International Business Machines Corp
Class: MU — unpublished motion picture other than a photoplay (numbering series begun 1946)
Finding: registration number MU66 also appears on another catalog entry with a different title; one of the two is misprinted or misread

The catalog entry has a problem (missing date, or a number that does not fit its year), so the renewal check cannot be relied on.
