Next Saturday (11th September 2010) there is an HPCC mini-conference in London. This is not a classic computing event really (which is why it's OT), but it is somewhat traditional for one of the talks to cover a classic HP computer or calculator, and anyway, there will be older machines to look at... Non-members of HPCC are welcome to attend, but please let a member of the committee (e.g. me) know if you are likely to come. More details are on the hpcc web site, http://www.hpcc.org/ -tony
