    I remember the KIM-1 from my teens. It was one of the first candidates on my list for buying a hobbyist computer. It never happened though. I bought a Tangerine Microtan 65 kit instead.

    Fantastic build Lee! I love this kit from "TripleD". I've had one, in the box, for I'm embarrassed to say how long. I really need to get it built. I may also need to check out this errata for the segmented led brightness. If you get time (which I doubt ha!) check out Jim Butterfield's lunar lander program for it. It's pretty neato to play on the keypad/display. Looking forward to seeing how the fundraising goes. If last year is any indication I bet things will smash through the roof and there will be donkey's all around! Take care!
