Viktor's amazing 4-bit processor

[Alan]

"I've been a software guy all my life. However, I was always fascinated by electronics, and part of my success as a programmer was due to my thorough understanding of how computers work.

Back in 1999, I put that understanding to the ultimate test: I actually designed, and built, a simple but functional 4-bit computer from low-level electronic components (TTL logic gates.) Although this machine has less then one tenth of a percent of the speed and one millionth of the memory of a modern Pentium system, not to mention that its "user interface" is just a set of miniature switches and blinking LED lights, I still consider this a proud accomplishment."

You are the UberGeek! I bow before you. I've never designed a circuit with more than six components that did anything other than smoke or explode.
