More on TTL Computer

I'm not the only one with a home built TTL computer.  Some other folks have spent years and done incredible work.  Check out projects like the Gigatron and Magic 1 from the links here

Here's a couple better pictures of the front panel of my silver box TTL computer.

One front panel light (LED) is connected to a 3909 circuit.  That's a special low power blinker that just blinks the light every second or two for over a year.  That's the first thing to get running.
