The Kenbak-1 was designed in the early 70s as an educational tool. The prototype was first demonstrated at a high school teacher convention in 1971. John Blankenbaker designed this computer before there were microprocessors. The board uses 132 standard series TTL logic ICs as the CPU / process control logic and two 1024 bit shift registers for memory. Even though the computer had a 1MHz clock it only processed a few hundred instructions per second! This is because the Kenbak-1 has a serial architecture, it only processes one bit at a time! We'll get into this later...
In 1987 out of several other vintage computer choices the Kenbak-1 was judged to be the first personal computer (PC)! This was the first machine you could buy, set on a table top, enter in a program, and view the results.
For a more in depth history of the Kenbak-1, what better place to hear it from than John himself! Click here for a link to his site!

It is possible that there will be fully assembled Kenbak-1 Series-2 kits available. I am not sure what the price would be yet (I would not be doing it).
The kit comes with a guarantee that you will end up with a fully functional unit. As long as you make a good effort at assembling the kit, and pay shipping both ways, I will diagnose and repair your kit for free. This guarantee does not cover physical damage to any part during or because of incorrect installation. Some parts, if damaged, cost so little that I would not charge for replacement. PCBs, Power supply, or the case for example would not be replaced for free. If you have any questions about this policy, please ask.
