Who might want my collections (but not yet!)?

Since my father passed away a couple of months ago I have been giving serious thoguth to making a formal wil myself (when my father was around, he would have known who to contact about various things). My first ;'choice' is to give everything to a personal friend who has been on this list. He shares enough of my interests that he will realise what is valuable and what is perhaps not so valuable. But the problem is tha said friend is about the same age as me, and it is not certainn he wil loutlive me. Of course if he passes away long before me, I can producve a new will, but it is worth putting a clause in the one I am currently writing to say what happens if he is not around. Now, as well as my classic computers there's also cmaeras, books, tools, test gear, other electronci stuff, etc. I would rather leave everything to one person/orgnaisation (rather than say 'the classic computers go to <a>, the tools go to <b>, etc) or worse still 'I leave my PDP11/45 system to <foo>', etc. In the latter case if I have, say, swapped my 11/45 for an 11/790 at some point then <foo> gets nothing, even though it was probably my intention that he would get the 11/70. In the former case, there could be disputes as to what category certain things fall into -- is the 'Datacopy 300' (an early digital camera that needs a classic PERQ to run it) a 'classic computer peripheral' or a 'camera', for example. Does anyone have any serious suggestions for an organisation (and yes, I am considering computer museums here, no matyter what I may have said i nthe past) who would be prepared to take the lot and pass on that which was of no use to them to other organisations or enthusiasts?
