This is a collection of technical reference tables that I have been accumulating since I was a child. To some extent, the Wikipedia has rather overtaken this particular project. However, this pre-dates the Wikipedia by a couple of decades – 1973 to be precise. Though obviously there have been a lot of updates since then. Besides, I rather like having all this stuff in one easy-to-find location. Seems we still have a few readers who quite like it too.
