"When the microchip was born, it looked a little different, delivered by Jack Kilby of Texas Instruments the chip consisted of a strip of germanium with just one transistor and other components all glued onto the glass side."

Way back in the "dark ages" growing up, I got an educational electronics kit that had just such an integrated circuit on it. The components were big enough to identify without any help and were significantly bigger than today's surface mounted devices!!

It contained four or five resistors, a couple capacitors and one or two transistors and was about the size of one of today's smaller CPUs (produced a lot less heat, too!).
