Abstract
A means for presenting individual instructions from a group of predetermined instructions in a random fashion is provided by a random word generator and a binary counter which cooperate to address a programmable read-only memory which sequentially provides character forming potentials to a plurality of fluorescent character display indicators so that each indicator receives the same character forming potentials at each step in the sequence in combination with a binary decoder responsive to the binary counter for enabling only one of the indicators for each step in the sequence.
Claims12
A display generator, comprising:
- a programmable read-only memory, including addressable data;
- random word generator means for addressing said memory;
- counter means for addressing said memory;
- a plurality of character display means for producing alpha-numeric displays as a function of said memory addressable data;
- and
- decoder means responsive to said counter for enabling said plurality of character display means to provide a random, visual instruction.
A method for providing a display, including the steps of:
- generating a continuous sequence of pulses;
- generating a random word in response to said continuous sequence of pulses;
- enabling a plurality of row addresses in a programmable read-only memory with said random word;
- counting said sequence of pulses with a binary counter;
- sequentially addressing the columns of said programmable read-only memory by said binary counter;
- providing character forming potentials to a plurality of individual alpha-numeric display generators as a function of the row and column address selected in said programmable read-only memory;
- and
- sequentially enabling individual ones of said display indicators by decoding the output of said binary counter and as a function of said decoded output applying an enabling potential to each of said indicators in sequence in a mutually exclusive fashion so as to randomly display visual instructions.
