Tape Pulse Keyword
MIP bit 10 modifier, the bit that enables the tape pulse PIO12 input. Reset if N = 0, otherwise set. All MIP modifiers are both parameters and switches. If N is missing the bit is set and the mode is active. Terse abbreviation is the code's name for the input. The method of input is now restricted to the PIO12 inputs, see Input.
The Tape Pulse input was designed as an alternative Request input whose source was a VOX driven from an auditory tape.
