What do people consider to be the 'holy grails' of classic computer 
collecting? 

That is, what machines are :

a) Not known not to exist any more -- so we exclude things like ENIAC 
where there's aboslutely no chance of finding an original

b) Sufficiently uncommon to be a 'real find'

It would appear form the above that the PDP7 and PDP9 qualifiy. I would 
add the PERQ 2T4, possibly the HP9831 (the Australian site claims they're 
very rare, but I am not totally convinced).
