PERFORATED-TAPE PUNCH AND CONTROL, TYPE 75
The Teletype BRPE paper-tape punch perforates 5-, 7-, or 8-hole tape at
63.3 characters (lines) per second. Information to be punched on a line of
tape is loaded on an 8-bit buffer (PB) from the AC bits 10 through 17. The
Punch flag becomes a 1 at the completion of punching action, signaling
that new information may be read into Punch Buffer (PB)(and punching
initiated). The Punch flag is connected to the Program Interrupt and to
the iors instruction bit 2. The Punch instructions, iot series 02, are:
