Application 4463

16 bit ALU that uses full grizdale adder and bazil d flops to address and write into RAM, add or subtract from addressed number, and save into its slot. Postal system: Used rs nor arrays to decode 4 digits from any house to direct the minecart (mail) to any other address in the neighborhood. This included a muxer to prevent multiple user input, dynamic cart storage system, and a every address traveling down a single bus. A custom made 8 bit expandable BCD to binary converter. Keypad decodes into binary, first user input is saved, and looped into Grizdale adders shifted 3 times and once (first number times 8 plus first number times 2= x10). The shifted number is saved in preparation for the second user input. The calculated number is then looped and shifted to produce any binary number from bcd. I
