I have seen the museum at Bletchley Park (online only) and wasn't too impressed although I have been told it is very good, my museum will be (hopefully) be more hands on although some of my stuff I wouldn't want a lot of people messing with to be honest. There will be a lot of 8 bit stuff - such as sinclair, commodore, nintendo etc. and a few 16 bit machines.
I hadn't thought of the museum as a club as such but that is a fantastic idea, does anybody have a Dragon 32 or a Sam Coupe in the Leicestershire area that could be donated/on loan/given etc.
Thanks for the positiveness so far - good to see that people would/could be interested.
