Great game, and I love it, but while trying to make a RAM chip, I have realized that pins can only be either input or output depending on what side of the chip they are on. This is only a problem because I'm trying to use the same line to read and write data in and out of a chip.
Here I have a 1 bit read/write chip with the top pin being the data line, middle being write-enable, and bottom being read. I am trying to read the data in the register, but the "1" only is able to travel to be the input of the one-bit register, and not the input of this chip.
