A while ago, I had to give a course for beginners on computers. As an introduction to computers I gave the learners a bit of an history lesson. To make the history lesson more interesting, I showed them a lot of old computer parts and compared them to the same newer technology. The items below, are some of the things that I showed to the learners.

Hope you have enjoyed the trip down the lane of computers? Some of this stuff goes right back to the beginning of the PC. The first PC I had was the ZX81 computer in 1981. This computer worked on the basic language and also machine code. We have moved far since those days.
