Binary signal that travels down a single line of redstone. It can send 8 bits of information with only 0.3 seconds delay between each bit. Using a dual signal processor i was also able to decode each byte with only a few milliseconds delay between each one.
This can be used to send up to 256 different signals down 1 redstone line. It can also be used to store large amounts of RAM or ROM which only need 1 output line. By using this along side computers or redstone contraptions that use binary, it could communicate with other computers using only a single line of redstone.
The RAM has the ability to be programmed by redstone or even other RAM, could be interesting to see what people could come up with...
