This is pretty much 100% historic and for interest rather than use - though the information should be up to date for current products.
Although the previous version of this document has been available for a long time, I have radically simplified it and made it easier to use.
There are, inevitably, bits missing and, I'm sure, some mistakes. If you are able to correct anything, or provide information to fill any gaps, please let me know.
