Definitions

  • the multiplexors 93 are connected in parallel and may consist of eight TI 74151 chips which are capable of accepting six groups of eight bits each from a counter so as to properly order in the data from the multiplexors through the buss terminal 95 to the processor 90.
  • the processor 90 may be an Intel 8039 128 byte processor which has its output from port 2 applied to a 2K byte program memory.
  • Communication lines 99 extend between port O of the processor 90 to the memory 100 and to a digital display 102.
  • a preferred counter control circuit 80 has three flip flop latches 104, 105 and 106 in combination with AND gates 107, 108, 109, 110 and 111 in combination with the gates 84 and 85 to enable the reference and movable counter circuits 81 and 82.
