See beggining of thread. Addition is simple, but requires more parts (think

not an architecture expert - i think I'm kind'a locked into reproducing
binary. But you're right, it does look like a non-starter...
I think it would be more interesting if silicon wasn't so cheap, as it
is base 2 makes it quite simple. I think the addition would be more than
0 1 and carry, thats just a binary half adder.
The truth table for a trinary half adder would look like this.
| 0 | 1 | 2 |

0 | 0 | 1 | 2 |
1 | 1 | 2 | 10 |
2 | 2 | 10 | 11 |
Hey ho, back to valves :-)
