How would you manage to collect all those - and in good condition for a photo too. I reckon one of the beauties of these old 'calculators' is that they also presented other related info to you - and that built up knowledge. A good example of that (for me anyway, probably not very interesting for most) is the circular one that shows various chemical radical groups and their Infra-Red vibrational wave lengths - a sort of whole chapter of info in one quick circular movement of the calculator. They're a bit like looking at a paper map versus finding an address in Google maps or somesuch. The latter doesn't give you any context of where you are or how to get there. Greg
