As someone who runs a museum - The Personal Computer Museum
(
www.pcmuseum.ca) in Brantford, Ontario, Canada I can tell you that it's a
lot more work than you might think to get it going, keep it running, etc.
As stated, there are many issues beyond just getting the place going. It
depends on local laws as well. I'm currently a not-for-profit organization
with "charitable objects". My "Charitable status" is still in the
works and
takes months. Getting it means a lot for those who donate computers and
money, and in some cases for certain grants it is an absolute requirement.
There are also "museum standards" that must be adhered to. Policies on how
you manage the collection and everything else about it.
We are JUST starting to get international attention and are growing - but
I've been at it for almost 3 years of being open and I've been collecting
for over 20. I am hoping to be at it full time by next year--but it's a
SLOW process.
If you wish to talk to me about it privately, email me at sbolton at
bfree.on.ca and I'd be more than happy to share my experiences.
