Reference tables
This is a collection of technical reference tables that I have been accumulating since I was a child. To a large extent, sites such as the Wikipedia have rather surpassed 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.

all the data from our database tables plus a few extras in a handy web applet. 
I have tried very hard to ensure the accuracy of these tables. However, they are supplied as-is without any warranty, express or implied!
