Pack- Punch Processor and Reader © 1965 DECUS [Digital Equipment Computer Users' Society]
The processor converts a standard binary-format tape into a more compressed format, with two twelve-bit words contained on every three lines of tape. Checksums are punched at frequent intervals, with each origin setting or at least every 200 words.
