As a teenager, I built fascinating and wondrous circuits using just a few transistors. My flashlight controlled relay could control a buzzer; music from my cassette tape player played on my radio with a two-transistor circuit; my amplifier could drive a speaker. These circuits were from dusty hobby books found at my local library with names like "29 transistor circuits" or "electronic hobby circuits."

To return to those glory days, I decided to build a digital clock using only transistors as the active elements. After a few years of “work” (it felt more like play), the final parts count is 194 transistors, 566 diodes, 400 resistors, and 87 capacitors ...
